http://git.postgresql.org/pg/commitdiff/772a5f1e5b343d07e907ef7f36fa36d190d55912

- In pg_upgrade, clean up handling of invalid directory specification
   by checking the stat() errno value more strictly.
 
http://git.postgresql.org/pg/commitdiff/1f35944607f1ede7dbb1dc3283d955b96f04ea5e

Tom Lane pushed:

- Fix pg_dump's handling of extension-member casts and languages.
   pg_dump has some heuristic rules for whether to dump casts and
   procedural languages, since it's not all that easy to distinguish
   built-in ones from user-defined ones.  However, we should not apply
   those rules to objects that belong to an extension, but just use the
   perfectly well-defined rules for what to do with extension member
   objects.  Otherwise we might mistakenly lose extension member
   objects during a binary upgrade (which is the only time that we'd
   want to dump extension members).
 
http://git.postgresql.org/pg/commitdiff/b3bc63efbc258874b06586aa7548fce37f3581e1

- Make plpgsql provide the typmods for its variables to the main
   parser.  Historically we didn't do this, even though we had the
   information, because plpgsql passed its Params via SPI APIs that
   only include type OIDs not typmods.  Now that plpgsql uses parser
   callbacks to create Params, it's easy to insert the right typmod.
   This should generally result in lower surprise factors, because a
   plpgsql variable that is declared with a typmod will now work more
   like a table column with the same typmod.  In particular it's the
   "right" way to fix bug #6020, in which plpgsql's attempt to return
   an anonymous record type is defeated by stricter record-type
   matching checks that were added in 9.0.  However, it's not
   impossible that this could result in subtle behavioral changes that
   could break somebody's existing plpgsql code, so I'm afraid to
   back-patch this change into released branches.  In those branches
   we'll have to lobotomize the record-type checks instead.
 
http://git.postgresql.org/pg/commitdiff/219dfae4e1b0ca7cbc0b2f0f7740e01657964c07

Peter Eisentraut pushed:

- /contrib/foo -> contrib/foo Since contrib is a relative directory
   specification, a leading slash is inappropriate.
 
http://git.postgresql.org/pg/commitdiff/0ee391b77a8aef3835a39ecc4856a9ab79936f56

- Spell checking and markup refinement
 
http://git.postgresql.org/pg/commitdiff/c13dc6402b6e99af9a8b7794e44d62deecafc745

- Remove obsolete comment
 
http://git.postgresql.org/pg/commitdiff/4a6a5c86db7362993a13b32bb0c02c956d94ff13

- Consistent spacing for lengthy error messages.  Also, we removed the
   display of the current value of max_connections/MaxBackends from
   some messages earlier, because it was confusing, so do that in the
   remaining one as well.
 
http://git.postgresql.org/pg/commitdiff/bb46d42859f62d5fbe8a8b55690643cba65e106c

- Rename pg_dump --no-security-label to --no-security-labels Other
   similar options also use the plural form.
 
http://git.postgresql.org/pg/commitdiff/c8e0c321194c985a13e7c7e4d3110ac032517350

- Fix untranslatable assembly of libpq connection failure message.
   Even though this only affects the insertion of a parenthesized word,
   it's unwise to assume that parentheses can pass through
   untranslated.  And in any case, the new version is clearer in the
   code and for translators.
 
http://git.postgresql.org/pg/commitdiff/fcd4575905608a6dd0868bd6ab99f3e06a743152

- Update config.guess and config.sub
 
http://git.postgresql.org/pg/commitdiff/8d8954938094744ef4cab9d6f45f8e9e8abeb58f

- Message style improvements
 
http://git.postgresql.org/pg/commitdiff/bcf63a51e3dbf7cdb70af03ed13e6984dee41ec0

- Message improvement
 
http://git.postgresql.org/pg/commitdiff/8932e2810034c43daa07c6da914a4c5ba46f6bd6

- Clarify the documentation of the --with-ossp-uuid option
 
http://git.postgresql.org/pg/commitdiff/51ad1784ccf9c2a72238a50a314771e34721f1d3

- Put documentation of backslash commands back in alphabetical order
 
http://git.postgresql.org/pg/commitdiff/7920d033d8b580f00ede0628ee0b1c3a3f3c6b43

- Message style improvements
 
http://git.postgresql.org/pg/commitdiff/fae625e7b9824ec64f770904108089ff4fbcf093

- Put lists in sensible order
 
http://git.postgresql.org/pg/commitdiff/60497722ac6d69d8ff82fe328b0a128e73433bec

Heikki Linnakangas pushed:

- Replace strdup() with pstrdup(), to avoid leaking memory.  It's been
   like this since the seg module was introduced, so backpatch to 8.2
   which is the oldest supported version.
 
http://git.postgresql.org/pg/commitdiff/ea896da394cbb0fb32a4b41065ea04b81c4b03f6

- In binary-upgrade mode, dump dropped attributes of composite types.
   Noah Misch
 
http://git.postgresql.org/pg/commitdiff/27c7875d95cf629e3f344ba91d1f8a1a936ed043

- Reset per-tuple memory context between every row in a scan node,
   even when there's no quals or projections. Currently this only
   matters for foreign scans, as none of the other scan nodes litter
   the per-tuple memory context when there's no quals or projections.
 
http://git.postgresql.org/pg/commitdiff/0319da638f337cae66a4649581dc1f33d5079e1a

- Pull up isReset flag from AllocSetContext to MemoryContext struct.
   This avoids the overhead of one function call when calling
   MemoryContextReset(), and it seems like the isReset optimization
   would be applicable to any new memory context we might invent in the
   future anyway.  This buys back the overhead I just added in previous
   patch to always call MemoryContextReset() in ExecScan, even when
   there's no quals or projections.
 
http://git.postgresql.org/pg/commitdiff/30e98a7e6e4869a7d6b3748ac9770bb8d69a8b26

Alvaro Herrera pushed:

- Fix declaration of $_TD in "strict" trigger functions.  This was
   broken in commit ef19dc6d39dd2490ff61489da55d95d6941140bf by the
   Bunce/Hunsaker/Dunstan team, which moved the declaration from
   plperl_create_sub to plperl_call_perl_trigger_func.  This doesn't
   actually work because the validator code would not find the variable
   declared; and even if you manage to get past the validator, it still
   doesn't work because get_sv("_TD", GV_ADD) doesn't have the expected
   effect.  The only reason this got beyond testing is that it only
   fails in strict mode.  We need to declare it as a global just like
   %_SHARED; it is simpler than trying to actually do what the patch
   initially intended, and is said to have the same performance
   benefit.  As a more serious issue, fix $_TD not being properly
   local()ized, meaning nested trigger functions would clobber $_TD.
   Alex Hunsaker, per test report from Greg Mullane
 
http://git.postgresql.org/pg/commitdiff/6b449d9051651d3accfdce73e21cfd5e3d0e09a3

Robert Haas pushed:

- Fix race condition in CheckTargetForConflictsIn.  Dan Ports
 
http://git.postgresql.org/pg/commitdiff/74aaa2136d13d613ffcea3171781d2e0c65a2e10

Magnus Hagander pushed:

- Add example for replication in pg_hba.conf.  Selena Deckelmann
