free'd for every transaction or statement, respectively. This patch
puts these data structures into static memory, thus saving a few CPU
cycles and two malloc calls per transaction or (in isolation level
READ COMMITTED) per query.

* A few bug fixes
* fixes solaris compile and crash issue
* decouple vacuum analyze and analyze thresholds
* detach from tty (dameonize)
* improved logging layout
* more conservative default configuration
* improved, expanded and updated README
please apply and 1st convenience, or before code freeze which ever comes
first :-)
At this point I think I have brought pg_autovacuum and its client side
design as far as I think it should go. It works, keeping file sizes in
check, helps performance and give the administrator a fair amount
flexibility in configuring it.
Next up is to do the FSM based design that is integrated into the back
end.
p.s. Thanks to Christopher Browne for his help.

minute and a half to decode a 500Kb on a fairly fast machine. I think the
culprit is sscanf.
I attach a patch that replaces the function with one used to perform the same
task in pyPgSQL (a Python interface to PostgreSQL). This code was written by
Billy Allie, author of pyPgSQL. I've changed a few variable names to match
those in the original code and removed a bit of Pythonness.
Billy has kindly looked at the code and points out that it is slightly
stricter than the original implementation and if it encounters an invalid
bytea such as '\12C' it drops the unescape '\' and outputs '12C'.
The code is licensed by the author under a BSD license.
I've performed limited testing of the function by putting JPEGs into
PostgreSQL, extracting them using them using the new function and diffing
against the original files.
The new function is significantly faster on my machine with the JPEGs being
decoded in less than a second. I attach a modified libpq example program that
I used for my testing.

least-recently-used strategy from clog.c into slru.c. It doesn't
change any visible behaviour and passes all regression tests plus a
TruncateCLOG test done manually.
Apart from refactoring I made a little change to SlruRecentlyUsed,
formerly ClogRecentlyUsed: It now skips incrementing lru_counts, if
slotno is already the LRU slot, thus saving a few CPU cycles. To make
this work, lru_counts are initialised to 1 in SimpleLruInit.
SimpleLru will be used by pg_subtrans (part of the nested transactions
project), so the main purpose of this patch is to avoid future code
duplication.

not all SQL identifiers taken from command line arguments. We decided
years ago that that was a bad idea: identifiers taken from the command
line should be treated as literally correct. Remove the inconsistent
code that has crept in recently. Also fix pg_dump so that the combination
of --schema and --table does what you'd expect, namely dump exactly one
table from exactly one schema. Per gripe from Deepak Bhole of Red Hat.
some reading on the subject.
1) PostgreSQL uses ephemeral keying, for its connections (good thing)
2) PostgreSQL doesn't set the cipher list that it allows (bad thing,
fixed)
3) PostgreSQL's renegotiation code wasn't text book correct (could be
bad, fixed)
4) The rate of renegotiating was insanely low (as Tom pointed out, set
to a more reasonable level)
I haven't checked around much to see if there are any other SSL bits
that need some review, but I'm doing some OpenSSL work right now
and'll send patches for improvements along the way (if I find them).
At the very least, the changes in this patch will make security folks
happier for sure. The constant renegotiation of sessions was likely a
boon to systems that had bad entropy gathering means (read: Slowaris
/dev/rand|/dev/urand != ANDIrand). The new limit for renegotiations
is 512MB which should be much more reasonable.

I'd placed the check for newly created matching pk rows for on update no
action earlier than it needed to be so that it'd check even when the key
values hadn't changed. This patch moves it to after checking for NULLs
in the old row and comparing the values since the select's probably more
expensive.

protocol 3, then falls back to 2 if postmaster rejects the startup packet
with an old-format error message. A side benefit of the rewrite is that
SSL-encrypted connections can now be made without blocking. (I think,
anyway, but do not have a good way to test.)
catalog lookups when not in a transaction. This prevents bizarre
failures if someone tries to set a value for session_authorization in
postgresql.conf. Per report from Fernando Nasser.
extensions to support our historical behavior. An aggregate belongs
to the closest query level of any of the variables in its argument,
or the current query level if there are no variables (e.g., COUNT(*)).
The implementation involves adding an agglevelsup field to Aggref,
and treating outer aggregates like outer variables at planning time.
#define PG_ENCODING_BE_LAST PG_ISO_8859_8

but the last client encoding in the enum list is actually PG_GB18030 and
it seems that
#define PG_ENCODING_IS_CLIEN_ONLY(_enc) \
(((_enc) > PG_ENCODING_BE_LAST && (_enc) <= PG_ENCODING_FE_LAST)
can never be true.
I think the define should read
#define PG_ENCODING_FE_LAST PG_GB18030
On the other hand, perhaps no-one cares, because
PG_ENCODING_IS_CLIEN_ONLY is never used.
