3467b1a1f9 Fix bugs in interval-to-time conversion: HAVE_INT64_TIMESTAMP case did not
work at all, and neither case behaved sanely for negative intervals.

a499725469 Allow GROUP BY, ORDER BY, DISTINCT targets to be unknown literals,
silently resolving them to type TEXT.  This is comparable to what we
do when faced with UNKNOWN in CASE, UNION, and other contexts.  It gets
rid of this and related annoyances:
	select distinct f1, '' from int4_tbl;
	ERROR:  Unable to identify an ordering operator '<' for type unknown
This was discussed many moons ago, but no one got round to fixing it.

cb02610e50 Adjust nestloop-with-inner-indexscan plan generation so that we catch
some cases of redundant clauses that were formerly not caught.  We have
to special-case this because the clauses involved never get attached to
the same join restrictlist and so the existing logic does not notice
that they are redundant.

996fdb9af1 Cause GROUP BY clause to adopt ordering operators from ORDER BY when
both clauses specify the same targets, rather than always using the
default ordering operator.  This allows 'GROUP BY foo ORDER BY foo DESC'
to be done with only one sort step.

ef2ba42717 Attached is a patch that enhances the output of psql's HTML mode.
The output now validates as HTML 4.01 Strict, XHTML 1.0 strict,
and XHTML 1.1 (assuming you wrap it in a valid html/body document).

It also wraps the output of PGRES_COMMAND_OK if the HTML tag is on,
for full compliance: this is why html_escaped_print has to be
externalized.

---------------------------------------------------------------------------

here is a patch that allows CIDR netmasks in pg_hba.conf. It allows two
address/mask forms:

. address/maskbits, or
. address netmask (as now)

If the patch is accepted I will submit a documentation patch to cover
it.

This is submitted by agreement with Kurt Roeckx, who has worked on a
patch that covers this and other IPv6 issues.

acd1536d9f Up to now, SerializableSnapshot and QuerySnapshot are malloc'ed and
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.

9243664dd4 This patch updates pg_autovacuum in several ways:
* 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.

4e1f986098 I found the libpq function PGunescapeBytea a little slow. It was taking a
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.

0abe7431c6 This patch extracts page buffer pooling and the simple
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.
