Fix a couple of memory leaks in src/bin/pg_basebackup/. These have been introduced by 7fbe0c8, and could happen for pg_basebackup and pg_receivewal. Per report from Coverity for the ones in walmethods.c, I have spotted the ones in receivelog.c after more review.

Skip trailing whitespaces when parsing integer options. strtoint(), via strtol(), would skip leading whitespaces but the same rule was not applied for trailing whitespaces, leading to an inconsistent behavior.

Simplify matching pattern check in TAP tests of pg_receivewal. A check in the ZLIB portion of the test to match the name of a non-compressed partial segment with a completed compressed segment was using m//, while a simple equality check is enough. This makes the test a bit stricter without impacting its coverage.

Add support for SET ACCESS METHOD in ALTER TABLE. The logic used to support a change of access method for a table is similar to changes for tablespace or relation persistence, requiring a table rewrite with an exclusive lock of the relation changed. Table rewrites done in ALTER TABLE already go through the table AM layer when scanning tuples from the old relation and inserting them into the new one, making this implementation straight-forward. Note that partitioned tables are not supported as these have no access methods defined.

Add missing exit() in pg_verifybackup when failing to find pg_waldump. pg_verifybackup needs by default pg_waldump to check after a range of WAL segments required for a backup, except if --no-parse-wal is specified. The code checked for the presence of the binary pg_waldump in an installation and reported an error, but it forgot to properly exit(). This could lead to confusing errors reported.

Add some missing exit() calls in error paths for various binaries. The following changes are done: - In pg_archivecleanup, the cleanup of older WAL segments would never fail immediately. - In pgbench, the initialization of a thread barrier would not fail hard. - In pg_recvlogical, a stat() failure never got the call. - In pg_basebackup, two chmod() reported a failure without exit()'ing when unpacking some tar data freshly received. It may be possible to continue writing some data even after this failure, but that could be confusing to the user at the end. These are arguably bugs, but they would happen for code paths where a failure is unlikely going to happen, so no backpatch is done.

Enable TAP tests of pg_receivewal for ZLIB on Windows, take three. This reverts commit 6a2c532. fairywren and bowerbird failed those tests because of incorrect versions of ZLIB linked to, causing errors like SIGBREAKs that stopped buildfarm runs or EACCES failures when writing compressed WAL segments.

Fix incorrect comment for get_agg_clause_costs. Adjust the header comment in get_agg_clause_costs so that it matches what the function currently does. No recursive searching has been done ever since 0a2bc5d61. It also does not determine the aggtranstype like the comment claimed. That's all done in preprocess_aggref(). preprocess_aggref also now determines the numOrderedAggs, so remove the mention that get_agg_clause_costs also calculates "counts". Normally, since this is just an adjustment of a comment it might not be worth back-patching, but since this code is new to PG14 and that version is still in beta, then it seems worth having the comments match.

Remove seemingly unneeded include directory in MSVC scripts. This appears to have been added way back in ee3b4188a but it's a little unclear why the change made in that commit is even needed given that 320c7eb8c, dated 18 months earlier, added code to copy fmgroids.h to src/include/utils. amcheck seems to get away without adding the additional include directory, so perhaps dblink can get away with it too. This builds ok in my VS2017 environment, but the buildfarm may serve as a reminder about why ee3b4188a was required. There's only one way to find out for sure.

Doc: Clarify lock levels taken during ATTACH PARTITION. It wasn't all that clear which lock levels, if any, would be held on the DEFAULT partition during an ATTACH PARTITION operation. Also, clarify which locks will be taken if the DEFAULT partition or the table being attached are themselves partitioned tables. Here I'm only backpatching to v12 as before then we obtained an ACCESS EXCLUSIVE lock on the partitioned table. It seems much less relevant to mention which locks are taken on other tables when the partitioned table itself is locked with an ACCESS EXCLUSIVE lock.

Adjust MSVC build scripts to parse Makefiles for defines. This adjusts the MSVC build scripts to look at the compile flags mentioned in the Makefile to look for -D arguments in order to determine which constants should be defined in Visual Studio builds. One small anomaly that appeared as a result of this change is that the Makefile for the ltree contrib module defined LOWER_NODE, but this was not properly defined in the MSVC build scripts. This meant that MSVC builds would differ in case sensitivity in the ltree module when compared to builds using a make build environment. To maintain the same behavior here we remove the -DLOWER_NODE from the Makefile and just always define it in ltree.h for non-MSVC builds. We need to maintain the old behavior here as this affects the on-disk compatibility of GiST indexes when using the ltree type. The only other resulting change here is that REFINT_VERBOSE is now defined for the autoinc, insert_username and moddatetime contrib modules. Previously on MSVC, this was only defined for the refint module. This aligns the behavior to build environments using make as all 4 of these modules share the same Makefile.

Harden pg_stat_statements tests against CLOBBER_CACHE_ALWAYS. Turns out the buildfarm hasn't been testing this, which will soon change. Julien Rouhaud, per report from me Discussion: https://email@example.com https://git.postgresql.org/pg/commitdiff/0806d08d4626f0a71a4e83cb399ee965a8aac99b
Use the "pg_temp" schema alias in EXPLAIN and related output. This patch causes EXPLAIN output to refer to objects that are in the current session's temp schema with the "pg_temp" schema alias rather than that schema's actual name. This is useful for our own testing purposes since it will stabilize EXPLAIN VERBOSE output for such cases, allowing us to use that in regression tests. It should be less confusing for end users too. Since ruleutils.c needs to change behavior for this, the change also leaks into a few other users of ruleutils.c, for example pg_get_viewdef(). AFAICS that won't cause any problems. We did find that aggressively trying to change this behavior across-the-board would cause issues, but as long as "pg_temp" only appears within generated SQL text, I think it'll be fine. Along the way, make get_namespace_name_or_temp conform to the same API as get_namespace_name, ie that it returns a palloc'd string or NULL. The current behavior hasn't caused any bugs since no callers attempt to pfree the result, but if it gets more widespread usage that could become a problem.

In event triggers, use "pg_temp" only for our own temp schema. pg_event_trigger_ddl_commands used "pg_temp" to refer to any temp schema, not only that of the current backend. This seems like overreach. It's somewhat unlikely that DDL commands would refer to temp objects of other sessions to begin with, but if they do, "pg_temp" would be a most misleading way to display the action. While this seems like a bug, it's not quite out of the realm of possibility that somebody out there is expecting the current behavior. Hence, fix in HEAD, but don't back-patch.

Improve libpq's handling of OOM during error message construction. Commit ffa2e4670 changed libpq so that multiple error reports occurring during one operation (a connection attempt or query) are accumulated in conn->errorMessage, where before new ones usually replaced any prior error. At least in theory, that makes us more vulnerable to running out of memory for the errorMessage buffer. If it did happen, the user would be left with just an empty-string error report, which is pretty unhelpful. We can improve this by relying on pqexpbuffer.c's existing "broken buffer" convention to track whether we've hit OOM for the current operation's error string, and then substituting a constant "out of memory" string in the small number of places where the errorMessage is read out. While at it, apply the same method to similar OOM cases in pqInternalNotice and pqGetErrorNotice3. Back-patch to v14 where ffa2e4670 came in. In principle this could go back further; but in view of the lack of field reports, the hazard seems negligible in older branches.

Use elog, not Assert, to report failure to provide an outer snapshot. As of commit 84f5c2908, executing SQL commands (via SPI or otherwise) requires having either an active Portal, or a caller-established active snapshot. We were simply Assert'ing that that's the case. But we've now had a couple different reports of people testing extensions that didn't meet this requirement, and were confused by the resulting crash. Let's convert the Assert to a test-and-elog, in hopes of making the issue clearer for extension authors. Per gripes from Liu Huailing and RekGRpth. Back-patch to v11, like the prior commit.

Dean Rasheed pushed:
Allow numeric scale to be negative or greater than precision. Formerly, when specifying NUMERIC(precision, scale), the scale had to be in the range [0, precision], which was per SQL spec. This commit extends the range of allowed scales to [-1000, 1000], independent of the precision (whose valid range remains [1, 1000]). A negative scale implies rounding before the decimal point. For example, a column might be declared with a scale of -3 to round values to the nearest thousand. Note that the display scale remains non-negative, so in this case the display scale will be zero, and all digits before the decimal point will be displayed. A scale greater than the precision supports fractional values with zeros immediately after the decimal point. Take the opportunity to tidy up the code that packs, unpacks and validates the contents of a typmod integer, encapsulating it in a small set of new inline functions. Bump the catversion because the allowed contents of atttypmod have changed for numeric columns. This isn't a change that requires a re-initdb, but negative scale values in the typmod would confuse old backends. Dean Rasheed, with additional improvements by Tom Lane. Reviewed by Tom Lane.

Fix corner-case errors and loss of precision in numeric_power(). This fixes a couple of related problems that arise when raising numbers to very large powers. Firstly, when raising a negative number to a very large integer power, the result should be well-defined, but the previous code would only cope if the exponent was small enough to go through power_var_int(). Otherwise it would throw an internal error, attempting to take the logarithm of a negative number. Fix this by adding suitable handling to the general case in power_var() to cope with negative bases, checking for integer powers there. Next, when raising a (positive or negative) number whose absolute value is slightly less than 1 to a very large power, the result should approach zero as the power is increased. However, in some cases, for sufficiently large powers, this would lose all precision and return 1 instead of 0. This was due to the way that the local_rscale was being calculated for the final full-precision calculation: local_rscale = rscale + (int) val - ln_dweight + 8 The first two terms on the right hand side are meant to give the number of significant digits required in the result ("val" being the estimated result weight). However, this failed to account for the fact that rscale is clipped to a maximum of NUMERIC_MAX_DISPLAY_SCALE (1000), and the result weight might be less then -1000, causing their sum to be negative, leading to a loss of precision. Fix this by forcing the number of significant digits calculated to be nonnegative. It's OK for it to be zero (when the result weight is less than -1000), since the local_rscale value then includes a few extra digits to ensure an accurate result. Finally, add additional underflow checks to exp_var() and power_var(), so that they consistently return zero for cases like this where the result is indistinguishable from zero. Some paths through this code already returned zero in such cases, but others were throwing overflow errors. Dean Rasheed, reviewed by Yugo Nagata.

This defeats using a symlinked shorter path to a longer path, and makes certain tests fail. We therefore call perl2host on the parent directory of the symlink and thereafter just use that result. Apply to release 14 where the problem has been observed. https://git.postgresql.org/pg/commitdiff/b35a67bc04243da609843949c53e6841e748243a
Make TestLib::perl2host more consistent and robust. Sometimes cygpath has been observed to return a path with a trailing slash. That can cause problems, Also, make "cygpath" usage consistent with "pwd -W" with respect to the use of forward slashes.

Avoid using ambiguous word "non-negative" in error messages. The error messages using the word "non-negative" are confusing because it's ambiguous about whether it accepts zero or not. This commit improves those error messages by replacing it with less ambiguous word like "greater than zero" or "greater than or equal to zero". Also this commit added the note about the word "non-negative" to the error message style guide, to help writing the new error messages. When postgres_fdw option fetch_size was set to zero, previously the error message "fetch_size requires a non-negative integer value" was reported. This error message was outright buggy. Therefore back-patch to all supported versions where such buggy error message could be thrown.

Update minimum recovery point on truncation during WAL replay of abort record. If a file is truncated, we must update minRecoveryPoint. Once a file is truncated, there's no going back; it would not be safe to stop recovery at a point earlier than that anymore. Commit 7bffc9b7bf changed xact_redo_commit() so that it updates minRecoveryPoint on truncation, but forgot to change xact_redo_abort(). Back-patch to all supported versions.
