07009651ce Repair roundoff-error problem for stddev/variance results near zero, 
per complaint from Kemin Zhou.
Fix lack of precision in numeric stddev/variance.

63cc56de54 Suppress subquery pullup and pushdown when the subquery has any 
set-returning functions in its target list.  This ensures that we
won't rewrite the query in a way that places set-returning functions
into quals (WHERE clauses).  Cf. bug reports from Joe Conway.

584f818bef Declare LWLock pointers as volatile to prevent AIX compiler from 
reordering operations at its whim.  Releasing TAS lock before we've
finished updating proc structure is uncool.

9f8ff2ab5a Re-enable SunOS4 port. Replace 
RTLD_LAZY | RTLD_GLOBAL to 1.
It seems sunos4.h was accidentally modified between 7.1 and 7.2.

969cc16c69 Enforce restriction that COPY DELIMITERS string must be exactly one 
character; replace strchr() search with simple comparison to speed up
COPY IN.  Per discussion in pghackers.

a0734d1eb1 Change appendStringInfoChar to appendStringInfoCharMacro in a couple of 
hot spots --- buys about 10% in Verner's INSERT example.

f4bd04bb67 Replace pq_getbytes(&ch, 1) calls with pq_getbyte(), which is easier 
to use and significantly faster.  This tweak saves 25% (!) of the runtime
of COPY IN in a test with 8000-character lines.  I wouldn't normally
commit a performance improvement this late in the cycle, but 25% got
my attention...

dae887abfe Remove now-dead code for processing CONSTR_UNIQUE nodes in 
AlterTableAddConstraint.  Earlier reorganization of the parser's
processing of ALTER TABLE means that these node types no longer get here.

636a939fe5 Fix array_out's failure to backslash backslashes, per bug# 524. Also, 
remove brain-dead rule that double quotes are needed if and only if the
datatype is pass-by-reference; neither direction of the implication holds
water.  Instead, examine the actual data string to see if it contains
any characters that force us to quote it.
Add some documentation about quoting of array values, which was previously
explained nowhere AFAICT.

2337780e0e Change display of FieldSelect nodes from arg.field to field(arg), 
per bug report from Stefan Hadjistoytchev.  There are some cases
where the dot notation works, but there are more where it doesn't.
Eventually ought to consider fixing the parser to allow cases like
func().field, but for now this is the simplest patch.

cd255bb070 Fix boundary condition in btbulkdelete: don't examine high key in case 
where rightmost index page splits while we are waiting to obtain exclusive
lock on it.  Not clear this would actually hurt (probably the callback
would always fail), but better safe than sorry.
Also, improve comments describing concurrency considerations in this code.

2985286eb4 I think it's patch's size problem that I can't 
send patches to pgsql-patches list.
the zh_CN NLS patch is about 80K,
but sended twice and still can emerge on list.
so I've put it at:

http://laser.zhengmai.com.cn/download/zh_CN.po.diff.tar.gz

If possible, please download it and apply it.
(for current CVS).

6b516f5951 Fix performance problems in TOAST compressor. The management of 
search lists was broken in such a way that only the most recent
instance of a given hash code would ever be searched, thus possibly
missing longer matches further back.  Fixing this gave 5 to 10%
compression improvement on some text test cases.  Additional small
tweaks to improve speed of inner loops a little bit.  There is no
compatibility issue created by this change, since the compressed data
format and decompression algorithm don't change.

c845b4272c IsSystemRelationName() treats TOAST relations as system relations. 
This seems the right thing for most usages, but I notice two places
where it is the wrong thing.  One is that the default permissions on
TOAST rels should be no-access, not world-readable; the other is that
PrepareForTupleInvalidation doesn't really need to spend time looking
at tuples of TOAST relations.
