for LC_MESSAGES; instead, just press forward, leaving the effective setting
at 'C'. There is not any very good reason to complain when we are going
to replace the value soon with whatever postgresql.conf says. This change
should solve the occasionally-reported problem of initdb failing with
'failed to initialize lc_messages'; the current theory is that that is
a reflection of either wrong LANG/LC_MESSAGES or completely broken locale
support.
and there's only one place that's a kluge, ie, appendStringLiteralConn.
Note that pg_dump itself doesn't use appendStringLiteralConn, so its
behavior is not affected; only the other utility programs care.
It required some changes in lexize algorithm, but interface with
dictionaries stays compatible with old dictionaries.

o turns off escape_string_warning in pg_dumpall.c
o optionally use E'' for \password (undocumented option?)
o honor standard_conforming-strings for \copy (but not
support literal E'' strings)
o optionally use E'' for \d commands
o turn off escape_string_warning for createdb, createuser,

as this seems only likely to create headaches for module developers. Put
the macro in the pre-existing fmgr.h file instead. Avoid being too cute
about how many fields we can cram into a word, and avoid trying to fetch
from a library we've already unlinked.
Along the way, it occurred to me that the magic block really ought to be
'const' so it can be stored in the program text area. Do the same for
the existing data blocks for PG_FUNCTION_INFO_V1 functions.
It now only checks four things:
Major version number (7.4 or 8.1 for example)
NAMEDATALEN
FUNC_MAX_ARGS
INDEX_MAX_KEYS
The three constants were chosen because:
1. We document them in the config page in the docs
2. We mark them as changable in pg_config_manual.h
3. Changing any of these will break some of the more popular modules:
FUNC_MAX_ARGS changes fmgr interface, every module uses this NAMEDATALEN
changes syscache interface, every PL as well as tsearch uses this
INDEX_MAX_KEYS breaks tsearch and anything using GiST.

Add dynamic record inspection to PL/PgSQL, useful for generic triggers:
tval2 := r.(cname);
or
columns := r.(*);

versions of OpenSSL. If your OpenSSL does not contain SHA2, then there
should be no conflict. But ofcourse, if someone upgrades OpenSSL,
server starts crashing.
Backpatched to 8.1.X.

An article at WebProNews quoted from the PG docs as to the merits of
stored procedures. I have added a bit more material on their merits,
as well as making a few changes to improve the introductions to
PL/Perl and PL/Tcl.

Delay write of pg_stats file to once every five minutes, during
shutdown, or when requested by a backend:
It changes so the file is only written once every 5 minutes (changeable
of course, I just picked something) instead of once every half second.
It's still written when the stats collector shuts down, just as before.
And it is now also written on backend request. A backend requests a
rewrite by simply sending a special stats message. It operates on the
assumption that the backends aren't actually going to read the
statistics file very often, compared to how frequent it's written today.
