== Angewandte Patches ==

Bruce Momjian pushed:

- In pg_upgrade, add status message about superuser check.
 
http://git.postgresql.org/pg/commitdiff/78318d63d7613ca9fe2206c717c7ccb400038db6

- Update documentation to state there is three-value logic, not
   three-value boolean logic.  Backpatch to 9.0.X since we just got
   another bug report about this today.
 
http://git.postgresql.org/pg/commitdiff/832c095d686e89f6390e0ff3e91b4c8015c2c3f7

- Documentation cleanup for the possible values of the datatype
   'boolean'.
 
http://git.postgresql.org/pg/commitdiff/a9cc9df021f43a8ecda0924236d22a004baa7d13

- In pg_upgrade, remove suggestion of setting pg_hba.conf to 'trust',
   now that we report the libpq connection failure string.  Per
   suggestion from Robert Haas.
 
http://git.postgresql.org/pg/commitdiff/5059cf6ebf36bc9731b8394a1d2c9dba6cb50a3c

- For create/dropdb, only connect once to the server since we now have
   a shared description table for pg_database comments.  Also update
   comments about database name selection.
 
http://git.postgresql.org/pg/commitdiff/7ff7711919287a93f348023d77f9611633c9627c

- Mention "backslash" escape processing change in 9.1 release notes.
 
http://git.postgresql.org/pg/commitdiff/64cc297dc9875a6feb3a310038707b6119b775ca

Tom Lane pushed:

- Remove "make check" target in src/test/isolation/Makefile.  This
   doesn't work as expected because the isolationtester program
   requires libpq to already be installed.  While it works when you've
   already installed libpq, having to already have done "make install"
   defeats most of the point of a check with a temp installation.  And
   there are weird corner cases if the dynamic linker picks up an old
   libpq.so from system library directories.  Remove the target (or
   more precisely, make it print a helpful message) so people don't
   expect the case to work.
 
http://git.postgresql.org/pg/commitdiff/7886cc73ad12fb9b5a729b6c8152f11a309f5d65

- Be more wary in initdb's creation of platform-dependent collations.
   Discard any collation aliases that match the built-in pg_collation
   entries (ie, "default", "C", "POSIX").  Such aliases would be
   refused by a CREATE COLLATION command, but since initdb is injecting
   them via a simple INSERT, it has to make the corresponding check for
   itself.  Per Martin Pitt's report of funny behavior in a machine
   that had a bogus "C.UTF-8" locale.  Also, use E'' syntax for the
   output of escape_quotes, as per its header comment.
 
http://git.postgresql.org/pg/commitdiff/853c1750f91feaa6a72b29ae683c955ab6f4df70

- Adjust documentation with respect to "unknown" timezone setting.
   The recent cleanup of GUC assign hooks got rid of the kludge of
   using "unknown" as a magic value for timezone and log_timezone.  But
   I forgot to update the documentation to match, as noted by Martin
   Pitt.
 
http://git.postgresql.org/pg/commitdiff/1453cd8f82139a3e751c617dc6635f7b1c7abe14

- Prevent datebsearch() from crashing on base == NULL && nel == 0.
   Normally nel == 0 works okay because the initial value of "last"
   will be less than "base"; but if "base" is zero then the calculation
   wraps around and we have a very large (unsigned) value for "last",
   so that the loop can be entered and we get a SIGSEGV on a bogus
   pointer.  This is certainly the proximate cause of the recent
   reports of Windows builds crashing on 'infinity'::timestamp ---
   evidently, they're either not setting an active timezonetktbl, or
   setting an empty one.  It's not yet clear to me why it's only
   happening on Windows and not happening on any buildfarm member.  But
   even if that's due to some bug elsewhere, it seems wise for this
   function to not choke on the powerup values of
   timezonetktbl/sztimezonetktbl.  I also changed the copy of this code
   in ecpglib, although I am not sure whether it's exposed to a similar
   hazard.  Per report and stack trace from Richard Broersma.
 
http://git.postgresql.org/pg/commitdiff/2e82d0b396473b595a30f68b37b8dfd41c37dff8

- Be more explicit about the meaning of the change in
   standard_conforming_strings.
 
http://git.postgresql.org/pg/commitdiff/ea964a451e51a32b71d004d261874adb1e135066

- Clean up parsing of CREATE TRIGGER's argument list.  Use ColLabel in
   place of ColId, so that reserved words are accepted as if they were
   not reserved.  Also, remove BCONST and XCONST, which were never
   documented as allowed.  Allowing those exposes to users an
   implementation detail, namely the format in which the lexer outputs
   such constants, that seems unwise to expose.  No documentation
   change needed, since this just makes the code act more like you'd
   expect from reading the CREATE TRIGGER man page.  Per complaint from
   Szymon Guz and subsequent discussion.
 
http://git.postgresql.org/pg/commitdiff/6fc6686b48bc569b05ce711d18cf964498b217f2

- Split PGC_S_DEFAULT into two values, for true boot_val vs computed
   default.  Failure to distinguish these cases is the real cause
   behind the recent reports of Windows builds crashing on
   'infinity'::timestamp, which was directly due to failure to
   establish a value of timezone_abbreviations in postmaster child
   processes.  The postmaster had the desired value, but
   write_one_nondefault_variable() didn't transmit it to backends.  To
   fix that, invent a new value PGC_S_DYNAMIC_DEFAULT, and be sure to
   use that or PGC_S_ENV_VAR (as appropriate) for "default" settings
   that are computed during initialization.  (We need both because
   there's at least one variable that could receive a value from either
   source.) This commit also fixes ProcessConfigFile's failure to
   restore the correct default value for certain GUC variables if they
   are set in postgresql.conf and then removed/commented out of the
   file.  We have to recompute and reinstall the value for any GUC
   variable that could have received a value from PGC_S_DYNAMIC_DEFAULT
   or PGC_S_ENV_VAR sources, and there were a number of oversights.
   (That whole thing is a crock that needs to be redesigned, but not
   today.) However, I intentionally didn't make it work "exactly right"
   for the cases of timezone and log_timezone.  The exactly right
   behavior would involve running select_default_timezone, which we'd
   have to do independently in each postgres process, causing the whole
   database to become entirely unresponsive for as much as several
   seconds.  That didn't seem like a good idea, especially since the
   variable's removal from postgresql.conf might be just an accidental
   edit.  Instead the behavior is to adopt the previously active
   setting as if it were default.  Note that this patch creates an ABI
   break for extensions that use any of the PGC_S_XXX constants;
   they'll need to be recompiled.
 
http://git.postgresql.org/pg/commitdiff/e05b866447899211a0c2df31bf0671faac4fc3e5

- Fix write-past-buffer-end in ldapServiceLookup().  The code to
   assemble ldap_get_values_len's output into a single string wrote the
   terminating null one byte past where it should.  Fix that, and make
   some other cosmetic adjustments to make the code a trifle more
   readable and more in line with usual Postgres coding style.  Also,
   free the "result" string when done with it, to avoid a permanent
   memory leak.  Bug report and patch by Laurenz Albe, cosmetic
   adjustments by me.
 
http://git.postgresql.org/pg/commitdiff/8d0df2048f8c0663b41440eeaf73e8859c922e28

Peter Eisentraut pushed:

- Put options in more alphabetical order
 
http://git.postgresql.org/pg/commitdiff/94a8fde403d229ccd9c667722ab3af72278f994d

- Add bug report line to pg_upgrade --help output
 
http://git.postgresql.org/pg/commitdiff/4c78846cb3a0f7017ad96d4513f79b1401fba12b

- Put pg_test_fsync --help and --version output in line with
   conventions.  Foremost, it should go to stdout.
 
http://git.postgresql.org/pg/commitdiff/3a8dcd9a1f9bbe36478995b22de40967c0610149

- Add some punctuation
 
http://git.postgresql.org/pg/commitdiff/87631ac98df2e32cac22ddee7b9c37813ff3b161

- Format pg_upgrade --version in line with conventions
 
http://git.postgresql.org/pg/commitdiff/00fad9f6fef8ed166b183ad45a9bd863d965d81c

Heikki Linnakangas pushed:

- Shut down WAL receiver if it's still running at end of recovery.  We
   used to just check that it's not running and PANIC if it was, but
   that can rightfully happen if recovery stops at recovery target.
 
http://git.postgresql.org/pg/commitdiff/a0c8514149de92d48a8cf0f1a1458486851980a4

Alvaro Herrera pushed:

- Fix assorted typos
 
http://git.postgresql.org/pg/commitdiff/c6eb5740b3c352fb10bf61bb4465332ae6b28ab1

Robert Haas pushed:

- Kill stray "not".
 
http://git.postgresql.org/pg/commitdiff/c5ab8425be07f6a866ce84dc03f87d6924421e72

- More cleanup of FOREIGN TABLE permissions handling.  This commit
   fixes psql, pg_dump, and the information schema to be consistent
   with the backend changes which I made as part of commit
   be90032e0d1cf473bdd99aee94218218f59f29f1, and also includes a
   related documentation tweak.  Shigeru Hanada, with slight
   adjustment.
 
http://git.postgresql.org/pg/commitdiff/9bb6d9795253bb521f81c626fea49a704a369ca9

Andrew Dunstan pushed:

- Build and run isolation test programs under MSVC.
 
http://git.postgresql.org/pg/commitdiff/840826e36cd40e63a3af05d9b41dc65250bc7a7a

- Add missing check function lookup.
 
http://git.postgresql.org/pg/commitdiff/20bacc9560b29b33b6cad4e53c6a77e6c8a71c5d

- Fix bad macro call noticed by MSVC compiler.
