to the physical layout of the rowtype, ie, there are dummy arguments
corresponding to any dropped columns in the rowtype. We formerly had a
couple of places that did it this way and several others that did not.
Fixes Gaetano Mendola's "cache lookup failed for type 0" bug of 5-Aug.
of XLogInsert had the same sort of checkpoint interlock problem as
RecordTransactionCommit, and indeed I found some. Btree index build
and ALTER TABLE SET TABLESPACE write data outside the friendly confines
of the buffer manager, and therefore they have to take their own
responsibility for checkpoint interlock. The easiest solution seems to
be to force smgrimmedsync at the end of the index build or table copy,
even when the operation is being WAL-logged. This is sufficient since
the new index or table will be of interest to no one if we don't get
as far as committing the current transaction.
therefore starting with GetCurrentTransactionId is wrong. Fixes
miscomputation of RecentGlobalXmin leading to bizarre behavior
reported by Gavin Sherry.
don't hold an open file reference to the original table at the end.
This is a good thing in any case, particularly so on Windows which
cannot drop the table file otherwise.
by the SQL standard. For backwards compatibility, however, continue to
accept the syntax without. Minor editorialization in the reference pages
for these commands, too.
and doesn't process forward slashes in the same way as external
commands. Quoting the first argument to COPY does not convert forward
to backward slashes, but COPY does properly process quoted forward
slashes in the second argument.
Win32 COPY works with quoted forward slashes in the first argument only if the
current directory is the same as the directory of the first argument.
for transaction commits that occurred just before the checkpoint. This is
an EXTREMELY serious bug --- kudos to Satoshi Okada for creating a
reproducible test case to prove its existence.
slashes to backslashes #ifdef WIN32. This is to cope with the fact
that Windows seems exceedingly unfriendly to slashes in shell commands,
as per recent discussion.
CurrentMemoryContext is DLLIMPORT on Win32. Work around that by
creating stubs in the backend for palloc/pstrdup.
Also fix pg_dumpall to do proper quoting on Win32.
was previously allowed in odd places with odd results now causes an ERROR.
Also changed behavior with respect to whitespace -- trailing whitespace is
now ignored as well as leading whitespace (which has always been ignored).
Documentation updated to reflect change in whitespace handling. Also some
refactoring to what I believe is a more sensible order of several paragraphs.
There won't be any, and in fact there won't even be an RTE for NEW,
which was leading to a core dump in CVS tip. 7.4 and earlier manage
not to crash when applying ResolveNew in this scenario, but I think
it was just good fortune that they didn't. Per report from
Bernd Helmle.
This avoids changing the displayed appearance of ACL columns now that
array_out decorates its output with bounds information when the lower
bound isn't one. Per gripe from Gaetano Mendola. Note that I did not
force initdb for this, although any database initdb'd in the last
couple of days is going to have some problems.
recommend that people go get Apache's rotatelogs program. Additional
benefits are that configuration is done through GUC, rather than
externally, and that the postmaster can monitor the log rotator and
restart it after failure (though we certainly hope that won't happen
often).
Andreas Pflug, some rework by Tom Lane.
subarrays of a given dimension have the same number of elements/subarrays.
Also repair a longstanding undocumented (as far as I can see) ability to
explicitly set array bounds in the array literal syntax. It now can
deal properly with negative array indicies. Modify array_out so that
arrays with non-standard lower bounds (i.e. not 1) are output with
the expicit dimension syntax. This fixes a longstanding issue whereby
arrays with non-default lower bounds had them changed to default
after a dump/reload cycle.
Modify regression tests and docs to suit, and add some minimal
documentation regarding the explicit dimension syntax.
dependency was looking at wrong columns and so would always fail.
Was not exposed by regression tests because we are only testing cases
involving built-in (pinned) types and so no actual dependency entry
exists to be removed.
and history files as per recent discussion. While at it, remove
pg_terminate_backend, since we have decided we do not have time during
this release cycle to address the reliability concerns it creates.
Split the 'Miscellaneous Functions' documentation section into
'System Information Functions' and 'System Administration Functions',
which hopefully will draw the eyes of those looking for such things.
