aggregated tuple of a run. Per report from Laurenz Albe. This is a new
bug in 8.4, but only because prior versions rejected SRFs in an Agg plan
node altogether.

This prevents autovacuum from reclaiming free space in them and causing
the test's output row order to change, which is causing intermittent
bogus failure reports in the buildfarm.
Backpatch to 8.3. The issue exists further back, but since autovacuum was
not on by default before 8.3, it's not a problem for buildfarm testing.

via hashing. Eventually we ought to make that possible, but it won't happen
for 8.4. Per yesterday's report from Robert Haas.

it's now entirely pseudo-SQL.

pg_migrator actually needs and not just a partial solution. We have to be
able to specify the OID that the new toast table should be created with.

function returning setof record. This used to work, more or less
accidentally, but I had broken it while extending the code to allow
materialize-mode functions to be called in select lists. Add a regression
test case so it doesn't get broken again. Per gripe from Greg Davidson.

rsinfo->expectedDesc == NULL in deflist_to_tuplestore(), but that doesn't
look very safe to me. Noted in passing while studying problem report
from Greg Davidson.

This same change was made in the backend a while ago; but it applies to
plpgsql as well.

node starts from the same place as the first scan did. This avoids surprising
behavior of scrollable and WITH HOLD cursors, as seen in Mark Kirkwood's bug
report of yesterday.
It's not entirely clear whether a rescan should be forced to drop out of the
syncscan mode, but for the moment I left the code behaving the same on that
point. Any change there would only be a performance and not a correctness
issue, anyway.
Back-patch to 8.3, since the unstable behavior was created by the syncscan
patch.

eg Japan. Report and fix by Itagaki Takahiro. Also fix CASHDEBUG printout
format for branches with 64-bit money type, and some minor comment cleanup.
Back-patch to 7.4, because it's broken all the way back.

In particular, always show 0 for the date type instead of null, and show
6 (the default) for time, timestamp, and interval without a declared
precision. This is now in fuller conformance with the SQL standard.
Also clarify the documentation about this.

more consistent with other cases, by having an unlabeled integer field
be treated as a number of minutes or seconds respectively. These cases
are outside the spec (which insists on full "dd hh:mm" or "dd hh:mm:ss"
input respectively), so it's not much help to us in deciding what to do.
But with this change, it's uniformly the case that an unlabeled integer
will be considered as being a number of the interval's rightmost field.
The change also takes us back to the 8.3 behavior of throwing error
for certain ambiguous inputs such as INTERVAL '1 2' DAY TO MINUTE.
Per recent discussion.

Sergey Burladyan, there are at least some dank corners of libxml2 that
assume this behavior, even though their published documentation suggests
they shouldn't.
This is only really a live problem in 8.3, but the code is still there
for possible debugging use in HEAD, so patch both branches.

will throw an error, rather than possibly allowing someone to synthesize
a manual call to an internal-accepting function. As of CVS HEAD and existing
releases, all such functions are either STRICT or careful about null inputs,
so there is no current security issue here. But it seems like a good idea
to lock this down to protect against future mistakes.
In passing, similarly lock down trigger_in, language_handler_in, opaque_in,
and shell_in. These are not believed to present any security risk, but
there's still no good reason to allow nulls of these types to be created.
I left the polymorphic pseudotypes (anyelement etc) alone, since a null
of one of those types doesn't seem to be a problem --- the worst you can
say about it is that it doesn't have an underlying non-polymorphic type.
If we were to make this change during normal development, we'd just
automatically bump catversion for a pg_proc.h change. But since this doesn't
create a compatibility risk and isn't believed to be fixing a live bug, it
seems better not to force a catversion bump in late beta.

"array_agg_finalfn(null)". We should modify pg_proc entries to prevent this
query from being accepted, but let's just make the function itself secure too.

behavior in cases where we don't know the heap tuple count accurately; in
particular partial vacuum, but this also makes the API a bit more useful
for ANALYZE. This patch adds "estimated_count" flags to both structs so
that an approximate count can be flagged as such, and adjusts the logic
so that approximate counts are not used for updating pg_class.reltuples.
This fixes my previous complaint that VACUUM was putting ridiculous values
into pg_class.reltuples for indexes. The actual impact of that bug is
limited, because the planner only pays attention to reltuples for an index
if the index is partial; which probably explains why beta testers hadn't
noticed a degradation in plan quality from it. But it needs to be fixed.
The whole thing is a bit messy and should be redesigned in future, because
reltuples now has the potential to drift quite far away from reality when
a long period elapses with no non-partial vacuums. But this is as good as
it's going to get for 8.4.

ifdef doesn't trigger. Not worth back-patching. Per buildfarm reports.

is supposed to remove duplicate heap TIDs, we have to be sure to reduce the
tuple size and posting-item count accordingly in addItemPointersToTuple().
Failing to do so resulted in the effective injection of garbage TIDs into the
index contents, ie, whatever happened to be in the memory palloc'd for the
new tuple. I'm not sure that this fully explains the index corruption
reported by Tatsuo Ishii, but the test case I'm using no longer fails.

should use GinItemPointerGetBlockNumber/GinItemPointerGetOffsetNumber,
not ItemPointerGetBlockNumber/ItemPointerGetOffsetNumber, because the latter
will Assert() on ip_posid == 0, ie a "Min" pointer. (Thus, ItemPointerIsMin
has never worked at all, but it seems unused at present.) I'm not certain
that the case can occur in normal functioning, but it's blowing up on me
while investigating Tatsuo-san's data corruption problem. In any case it
seems like a problem waiting to bite someone.
Back-patch just in case this really is a problem for somebody in the field.

Seems silly to ask translators to expend work on these, especially in
pluralized variants.

by extending the ereport() API to cater for pluralization directly. This
is better than the original method of calling ngettext outside the elog.c
code because (1) it avoids double translation, which wastes cycles and in
the worst case could give a wrong result; and (2) it avoids having to use
a different coding method in PL code than in the core backend. The
client-side uses of ngettext are not touched since neither of these concerns
is very pressing in the client environment. Per my proposal of yesterday.
