command strings inserts relative not absolute path of file to process.
This is a side-effect of 2005-07-04 change that makes the server use
relative paths in general. Noted by Bernd Helmle.
_bt_pagedel to recover from the failure: just search the whole parent level
if searching to the right fails. This does nothing for the underlying problem
that index keys became out-of-order in the grandparent level. However, we
believe that there is no other consequence worse than slightly inefficient
searching, so this narrow patch seems like the safest solution for the back
branches.
(blobs) with comments, per bug #2727 from Konstantin Pelepelin.
Mea culpa for not having tested this case.
Back-patch to 8.1; prior branches don't dump blob comments at all.
sin_port in the returned IP address struct when servname is NULL. This has
been observed to cause failure to bind the stats collection socket, and
could perhaps cause other issues too. Per reports from Brad Nicholson
and Chris Browne.
1) pgwin32_waitforsinglesocket(): WaitForMultipleObjectsEx now called with
finite timeout (100ms) in case of FP_WRITE and UDP socket. If timeout occurs
then pgwin32_waitforsinglesocket() tries to write empty packet goes to
WaitForMultipleObjectsEx again.
2) pgwin32_send(): add loop around WSASend and pgwin32_waitforsinglesocket().
The reason is: for overlapped socket, 'ok' result from
pgwin32_waitforsinglesocket() isn't guarantee that socket is still free,
it can become busy again and following WSASend call will fail with
WSAEWOULDBLOCK error.

rows --- if the surrounding query queued any trigger events between the rows,
the events would be fired at the wrong time, leading to bizarre behavior.
Per report from Merlin Moncure.
This is a simple patch that should solve the problem fully in the back
branches, but in HEAD we also need to consider the possibility of queries
with RETURNING clauses. Will look into a fix for that separately.
I introduced in 7.4.1 :-(. It's correct to allow unknown to be coerced to
ANY or ANYELEMENT, since it's a real-enough data type, but it most certainly
isn't an array datatype. This can cause a backend crash but AFAICT is not
exploitable as a security hole. Per report from Michael Fuhr.
Note: as fixed in HEAD, this changes a constant in the pg_stats view,
resulting in a change in the expected regression outputs. The back-branch
patches have been hacked to avoid that, so that pre-existing installations
won't start failing their regression tests.
attislocal = true, since they are not really inherited but merely copied
from the original table. I'm not sure if there are any cases where it makes
a real difference given the existing uses of the flag, but wrong is wrong.
This was fixed in passing in HEAD by the LIKE INCLUDING CONSTRAINTS patch,
but never back-patched.
Formerly they'd emit '^foo|bar$' which is wrong because the anchors are
parsed as part of the alternatives; must emit '^(foo|bar)$' to get expected
behavior. Same as bug found previously in similar_escape(). Already fixed
in HEAD, this is just back-porting the part of that patch that was a bug fix.
tried a variant file from resultmap and it didn't match. This is already done
in HEAD's C-code version, and is needed because OpenBSD has recently migrated
to a more standard handling of float underflow --- see buildfarm results
from emu.
quote chars inside quote marks, should emit one quote *and stay in inquotes
mode*. No doubt the lack of reports of this have something to do with the
poor documentation of the feature ...
overlapping possible matches for the separator string, such as
string_to_array('123xx456xxx789', 'xx').
Also, revise the logic of replace(), split_part(), and string_to_array()
to avoid O(N^2) work from redundant searches and conversions to pg_wchar
format when there are N matches to the separator string.
Backpatched the full patch as far as 8.0. 7.4 also has the bug, but the
code has diverged a lot, so I just went for a quick-and-dirty fix of the
bug itself in that branch.
been initialized yet. This can happen because there are code paths that call
SysCacheGetAttr() on a tuple originally fetched from a different syscache
(hopefully on the same catalog) than the one specified in the call. It
doesn't seem useful or robust to try to prevent that from happening, so just
improve the function to cope instead. Per bug#2678 from Jeff Trout. The
specific example shown by Jeff is new in 8.1, but to be on the safe side
I'm backpatching 8.0 as well. We could patch 7.x similarly but I think
that's probably overkill, given the lack of evidence of old bugs of this ilk.
and instead make the grammar production for the RETURN statement do the
heavy lifting. The lookahead idea was copied from the main parser, but
it does not work in plpgsql's parser because here gram.y looks explicitly
at the scanner's yytext variable, which will be out of sync after a
failed lookahead step. A minimal example is
create or replace function foo() returns void language plpgsql as '
begin
perform return foo bar;
end';
which can be seen by testing to deliver "foo foo bar" to the main parser
instead of the expected "return foo bar". This isn't a huge bug since
RETURN is not found in the main grammar, but it could bite someone who
tried to use "return" as an identifier.
Back-patch to 8.1. Bug exists further back, but HEAD patch doesn't apply
cleanly, and given the lack of field complaints it doesn't seem worth
the effort to develop adjusted patches.
when what's being executed is a COMMIT or ROLLBACK. Per report from
Sergey Koposov. Backpatch to 8.1; 8.0 and before don't have the bug
due to lack of any logging at all here.
as micro-seconds, rather than as 100 microseconds, as it does now. This
actually fixes all setitimer calls on Win32, but statement_timeout is
the most visible fix.
Backpatch to 8.1.X. 8.0 works as documented.
