(rd_att) field of a nailed-in-cache relcache entry. This fixes the bug
reported by Alvaro 8-Dec-2004; I believe it probably also explains
Grant Finnemore's report of 10-Sep-2004.
In an unrelated change in the same file, put back 7.4's response to
failure to rename() the relcache init file, ie, unlink the useless
temp file. I did not put back the warning message, since there might
actually be some reason not to have that.
of an inheritance child table is binary-compatible with the rowtype of
its parent, invent an expression node type that does the conversion
correctly. Fixes the new bug exhibited by Kris Shannon as well as a
lot of old bugs that would only show up when using multiple inheritance
or after altering the parent table.
better make sure the sort order is totally specified; else we get burnt
by platform-specific behavior of qsort() with equal keys. Per buildfarm

would always have truncated the identifier to NAMEDATALEN-1 already,
but let's be safe. Per report from Klocwork.

Great.
A follow-up patch for current CVS HEAD is attached, and available at
http://troels.arvin.dk/db/pgsql/conformance/pgsql-sql-conformance-
followup.patch
The patch
- includes a core feature ID that had been left
out by mistake (C011)
- updates the sql_feature_packages.txt table to
reflect changes in SQL:2003 which were not
covered properly in my last patch

the "ps" argument list on Unix - meaning that there is no way to
identify for example the stats processors or the bgwriter.
This patch adds this functionality, in a bit of a crufty way. It creates
a kernel Event object with the name of what would be in the title. This
can be viewed using for example Process Explorer.
It's been very handy for me during both debugging and using. I haven't
figured a better way, but perhaps someone has one that's less crufty? If
not, here is at least a working patch :-)

reasons I outlined in pghackers a few days ago.
Also, undo someone's overly optimistic decision to reduce tuple state
checks from if (...) elog() to Asserts. If I trusted this code more,
I might think it was a good idea to disable these checks in production
installations. But I don't.
escapes --- they aren't simply quoted characters. Problem noted by
Antti Salmela. Also fix problem with incorrect handling of multibyte
characters when followed by a quantifier.
In particular, there was a mathematical tie between the two possible
nestloop-with-materialized-inner-scan plans for a join (ie, we computed
the same cost with either input on the inside), resulting in a roundoff
error driven choice, if the relations were both small enough to fit in
sort_mem. Add a small cost factor to ensure we prefer materializing the
smaller input. This changes several regression test plans, but with any
luck we will now have more stability across platforms.
a relation's number of blocks, rather than the possibly-obsolete value
in pg_class.relpages. Scale the value in pg_class.reltuples correspondingly
to arrive at a hopefully more accurate number of rows. When pg_class
contains 0/0, estimate a tuple width from the column datatypes and divide
that into current file size to estimate number of rows. This improved
methodology allows us to jettison the ancient hacks that put bogus default
values into pg_class when a table is first created. Also, per a suggestion
from Simon, make VACUUM (but not VACUUM FULL or ANALYZE) adjust the value
it puts into pg_class.reltuples to try to represent the mean tuple density
instead of the minimal density that actually prevails just after VACUUM.
These changes alter the plans selected for certain regression tests, so
update the expected files accordingly. (I removed join_1.out because
it's not clear if it still applies; we can add back any variant versions
as they are shown to be needed.)
useful than just \'failed\' when there's a problem. Per gripe from
Chris Albertson.
In an unrelated change, use VACUUM FULL; VACUUM FREEZE; rather than
a single VACUUM FULL FREEZE command, to respond to my worries of a
couple days ago about the reliability of doing this in one go.

prevents problems when the DECLARE is in a portal and is executed
repeatedly, as is possible in v3 protocol. Per analysis by Oliver
Jowett, though I didn't use his patch exactly.
