delta/postgresql.git, branch REL7_3_12

Stamp 7.3.12.

2005-12-09T20:56:45+00:00

Add release notes for back branches (7.3 and up).

2005-12-09T20:41:11+00:00

Also minor improvements to 8.1.1 release notes.

Fix stupid bug with sizeof

2005-12-06T18:22:09+00:00

Add regression test to see if the min/max values of int8 convert correctly.

2005-12-05T04:14:39+00:00

Properly document return value of strpos().

2005-11-16T03:58:08+00:00

Fix longstanding race condition in transaction log management: there was a

2005-11-03T00:23:57+00:00

very narrow window in which SimpleLruReadPage or SimpleLruWritePage could
think that I/O was needed when it wasn't (and indeed the buffer had already
been assigned to another page).  This would result in an Assert failure if
Asserts were enabled, and probably in silent data corruption if not.
Reported independently by Jim Nasby and Robert Creager.

I intend a more extensive fix when 8.2 development starts, but this is a
reasonably low-impact patch for the existing branches.

Fix longstanding bug that would sometimes let the planner generate a bad plan

for an outer join; symptom is bogus error "RIGHT JOIN is only supported with
merge-joinable join conditions".  Problem was that select_mergejoin_clauses
did its tests in the wrong order.  We need to force left join not right join
for a merge join when there are non-mergeable join clauses; but the test for
this only accounted for mergejoinability of the clause operator, and not
whether the left and right Vars were of the proper relations.  Per report
from Jean-Pierre Pelletier.

Pass a strdup'd ident string to openlog(), to ensure that reallocation

of GUC memory doesn't cause us to start emitting a bogus ident string.
Per report from Han Holl.  Also some trivial code cleanup in write_syslog.

Fix longstanding bug found by Atsushi Ogawa: _bt_check_unique would mark

2005-10-12T17:18:45+00:00

the wrong buffer dirty when trying to kill a dead index entry that's on
a page after the one it started on.  No risk of data corruption, just
inefficiency, but still a bug.

Stamp release 7.3.11.
