in the current backend for the target table. These operations move tuples
around and would thus invalidate the TIDs stored in the trigger event records.
(We need not worry about events in other backends, since acquiring exclusive
lock should be enough to ensure there aren't any.) It might be sufficient
to forbid only the table-rewriting variants of ALTER TABLE, but in the absence
of any compelling use-case, let's just be safe and simple. Per follow-on
investigation of bug #3847, though this is not actually the same problem
reported therein.
Possibly this should be back-patched, but since the case has never been
reported from the field, I didn't bother.

a trigger's target table. The rowtype could change from one call to the
next, so cope in such cases, while avoiding doing repetitive catalog lookups.
Per bug #3847 from Mark Reid.
Backpatch to 8.2.x. Likely this fix should go further back, but I can't test
it because I no longer have a machine with a pre-2.5 Python installation.
(Maybe we should rethink that idea about not supporting Python 2.5 in the
older branches.)

since these seem to happen after all in corrupted indexes. Make sure we
supply the index name in all cases, and provide relevant block numbers where
available. Also consistently identify the index name as such.
Back-patch to 8.2, in hopes that this might help Mason Hale figure out his
problem.

Applied patch send by ITAGAKI Takahiro <itagaki.takahiro@oss.ntt.co.jp> to fix bug in connect statement if user name is a variable.
Also fixed test case that didn't detect this.

were reporting ERROR for interactive assignments and LOG for other cases,
some were saying nothing for non-interactive cases, and a few did yet other
things. Make them use a new function GUC_complaint_elevel() to establish
a reasonably uniform policy about how to report. There are still a few
edge cases such as assign_search_path(), but it's much better than before.
Per gripe from Devrim Gunduz and subsequent discussion.
As noted by Alvaro, it'd be better to fold these custom messages into the
standard "invalid parameter value" complaint from guc.c, perhaps as the DETAIL
field. However that will require more redesign than seems prudent for 8.3.
This is a relatively safe, low-impact change that we can afford to risk now.

COPY. We need a restriction here because when the delimiter occurs as a
data character, it is emitted with a backslash, and that will only work
as desired if CopyReadAttributesText() will interpret the backslash sequence
as representing the second character literally. This is currently untrue
for 'b', 'f', 'n', 'r', 't', 'v', 'x', and octal digits. For future-proofing
and simplicity of explanation, it seems best to disallow a-z and 0-9.
We must also disallow dot, since "\." by itself would look like copy EOF.
Note: "\N" is by default the null print string, so N would also cause a
problem, but that is already tested for.

This prevented gettext from recognizing the strings that need to be
translated.

CopyAttributeOutText(), so that control characters are converted to the
C-style escape sequences even if they happen to be equal to the column
delimiter (as is true by default for tab, for example). Oversight in my
previous patch to restore pre-8.3 behavior of COPY OUT escaping. Per report
from Tomas Szepe.

print the index key variable or expression for that column. It was mistakenly
printing ASC/DESC/NULLS FIRST/NULLS LAST decoration too --- and not only for
the target column, but all columns. Someday we should have an option to
extract that info (and the opclass decoration as well) for a single index
column ... but today is not that day. Per bug #3829 and subsequent
discussion.

The zero-point case is sensible so far as the data structure is concerned,
so maybe we ought to allow it sometime; but right now the textual input
routines for these types don't allow it, and it seems that not all the
functions for the types are prepared to cope.

psql's \d commands and other uses of printQuery(). Previously we would pass
these strings through gettext() and then send them to the server as literals
in the SQL query. But the code was not set up to handle doubling of quotes in
the strings, causing failure if a translation attempted to use the wrong kind
of quote marks, as indeed is now the case for (at least) the French
translation of \dFp. Another hazard was that gettext() would translate to
whatever encoding was implied by the client's LC_CTYPE setting, which might be
different from the client_encoding setting, which would probably cause the
server to reject the query as mis-encoded. The new arrangement is to send the
untranslated ASCII strings to the server, and do the translations inside
printQuery() after the query results come back. Per report from Guillaume
Lelarge and subsequent discussion.

useful and confuses people who think it is the same as -U. (Eventually
we might want to re-introduce it as being an alias for -U, but that should
not happen until the switch has actually not been there for a few releases.)
Likewise in pg_dump and pg_restore. Per gripe from Robert Treat and
subsequent discussion.

PQconnectionNeedsPassword function that tells the right thing for whether to
prompt for a password, and improve PQconnectionUsedPassword so that it checks
whether the password used by the connection was actually supplied as a
connection argument, instead of coming from environment or a password file.

the two join variables at both ends: not only trailing rows that need not be
scanned because there cannot be a match on the other side, but initial rows
that will be scanned without possibly having a match. This allows a more
realistic estimate of startup cost to be made, per recent pgsql-performance
discussion. In passing, fix a couple of bugs that had crept into
mergejoinscansel: it was not quite up to speed for the task of estimating
descending-order scans, which is a new requirement in 8.3.
