Seems cleaner to get the currently-replayed TLI in the same call to
GetXLogReplayRecPtr that we get the WAL position. Make it more clear in the
comment what the code does when recovery has already ended
(RecoveryInProgress() will set ThisTimeLineID in that case). Finally, make
resetting ThisTimeLineID afterwards more explicit.
This change makes type_func_name_keywords less reserved than they were
before, by allowing them for role names, language names, EXPLAIN and COPY
options, and SET values for GUCs; which are all places where few if any
actual keywords could appear instead, so no new ambiguities are introduced.
The main driver for this change is to allow "COPY ... (FORMAT BINARY)"
to work without quoting the word "binary". That is an inconsistency that
has been complained of repeatedly over the years (at least by Pavel Golub,
Kurt Lidl, and Simon Riggs); but we hadn't thought of any non-ugly solution
until now.
Back-patch to 9.0 where the COPY (FORMAT BINARY) syntax was introduced.
Make slightly better decisions about indentation than what pgindent
is capable of. Mostly breaking out long function calls into one
line per argument, with a few other minor adjustments.
No functional changes- all whitespace.
pgindent ran cleanly (didn't change anything) after.
Passes all regressions.
The documentation for ALTER TYPE .. RENAME claimed to support a
RESTRICT/CASCADE option at the 'type' level, which wasn't implemented
and doesn't make a whole lot of sense to begin with. What is supported,
and previously undocumented, is
ALTER TYPE .. RENAME ATTRIBUTE .. RESTRICT/CASCADE.
I've updated the documentation and back-patched this to 9.1 where it was
first introduced.
When COPY uses the multi-insert method to insert a batch of tuples into the
heap at a time, incorrect line number was printed if something went wrong in
inserting the index tuples (primary key failure, for exampl), or processing
after row triggers.
Fixes bug #8173 reported by Lloyd Albin. Backpatch to 9.2, where the multi-
insert code was added.
checkpointer needs to reset ThisTimeLineID after
a restartpoint to allow installing/recycling new
WAL files. If recovery has already ended this
would leave ThisTimeLineID set incorrectly and
so we must reset it otherwise later checkpoints
do not have the correct timeline.
Bug report by Heikki Linnakangas.
Further investigation by Heikki and myself.
In the primary_conninfo line that "pg_basebackup -R" generates, single
quotes in parameter values need to be escaped into \\'; the libpq parser
requires the quotes to be escaped into \', and recovery.conf parser requires
the \ to be escaped into \\.
Also, don't quote parameter values unnecessarily, to make the connection
string prettier. Most options in a libpq connection string don't need
quoting.
Reported by Hari Babu, closer analysis by Zoltan Boszormenyi, although I
didn't use his patch.
This simplifies the handling of crashes after fast promotion and various
minor cases that can exist in short timing windows around that case.
Broad fix to bug reported by Michael Paquier on -hackers,
approach prompted by Heikki Linnakangas
euc_* and mule_internal test cases were identical to the ones in
src/test/mb. sql_ascii didn't exist elsewhere, but has been broken since
2001, and doesn't seem very interesting anyway. drop.sql hasn't been used
since 2000, when regress.sh was removed.
Fixes oversight in commit 2ffa740be9.
Per report from Josh Kupershmidt.
I think we've broken this case before, so let's add a regression test
this time.
PathNameOpenFile failed to ensure that the correct value of errno was
returned to its caller after a failure (because it incorrectly supposed
that free() can never change errno). In some cases this would result
in a user-visible failure because an expected ENOENT errno was replaced
with something else. Bogus EINVAL failures have been observed on OS X,
for example.
There were also a couple of places that could mangle an important value
of errno if FDDEBUG was defined. While the usefulness of that debug
support is highly debatable, we might as well make it safe to use,
so add errno save/restore logic to the DO_DB macro.
Per bug #8167 from Nelson Minar, diagnosed by RhodiumToad.
Back-patch to all supported branches.
The behavior is that the required sequence is created locally, which is
appropriate because the default expression will be evaluated locally.
Per gripe from Brad Nicholson that this case was refused with a confusing
error message. We could have improved the error message but it seems
better to just allow the case.
Also, remove ALTER TABLE's arbitrary prohibition against being applied to
foreign tables, which was pretty inconsistent considering we allow it for
views, sequences, and other relation types that aren't even called tables.
This is needed to avoid breaking pg_dump, which sometimes emits column
defaults using separate ALTER TABLE commands. (I think this can happen
even when the default is not associated with a sequence, so that was a
pre-existing bug once we allowed column defaults for foreign tables.)
If OID wraparound should occur while in standalone mode (unlikely but
possible), we want to advance the counter to FirstNormalObjectId not
FirstBootstrapObjectId. Otherwise, user objects might be created with OIDs
in the system-reserved range. That isn't immediately harmful but it poses
a risk of conflicts during future pg_upgrade operations.
Noted by Andres Freund. Back-patch to all supported branches, since all of
them are supported sources for pg_upgrade operations.
In a construct like "select plain_function(set_returning_function(...))",
the plain function is applied to each output row of the SRF successively.
If some of the SRF outputs are NULL, and the plain function is strict,
you'd expect to get NULL results for such rows ... but what actually
happened was that such rows were omitted entirely from the result set.
This was due to confusion of this case with what should happen for nested
set-returning functions; a strict SRF is indeed supposed to yield an empty
set for null input. Per bug #8150 from Erwin Brandstetter.
Although this has been broken forever, we're not back-patching because
of the possibility that some apps out there expect the incorrect behavior.
This change should be listed as a possible incompatibility in the 9.3
release notes.
The existing code in NUM_numpart_from_char has hard-wired logic to treat
'.' as decimal point, even when we're using a locale-aware format string
and the locale says that '.' is the thousands separator. This results in
clearly wrong answers in FM mode (where we must be able to identify the
decimal point location), as per bug report from Patryk Kordylewski.
Since the initialization code in NUM_prepare_locale already sets up
Np->decimal as either the locale decimal-point string or "." depending
on which decimal-point format code was used, there's really no need to
have any extra logic at all in NUM_numpart_from_char: we only need to
test for a match to Np->decimal.
(Note: AFAICS there's nothing in here that explicitly checks for thousands
separators --- rather, any unmatched character is silently skipped over.
That's pretty bogus IMO but it's not the issue being complained of.)
This is a longstanding bug, but it's possible that some existing apps
are depending on '.' being recognized as decimal point even when using
a D format code. Hence, no back-patch. We should probably list this
as a potential incompatibility in the 9.3 release notes.
Previously, the port number used in this test script was hard-wired at
pg_upgrade's default of 50432; which is not so great because parallel build
runs might conflict. Commit 3d53173e20
removed this setting for the postmasters started by the script proper
(not by pg_upgrade), which didn't do anything to fix that problem and also
guaranteed a failure if there was a live postmaster at the build's default
port number. Instead, select a non-conflicting temporary port number in
the same way that pg_regress.c does. (Its method isn't entirely
bulletproof, but given the lack of complaints I'm not going to worry
about that today.)
In passing, unset MAKEFLAGS and MAKELEVEL to avoid problems with the
script's internal invocations of make, for the same reason pg_regress.c
does: it could cause problems in a parallel make.
The 9.2 patch that added argument name support in SQL-language functions
missed updating a parenthetical comment about that in the CREATE FUNCTION
reference page. Noted by Erwin Brandstetter.
