47d6d641dd Include the platform "FAQs" into the installation instructions.
I weeded out some really old information along the way.
FAQ_AIX needs separate consideration and will be dealt with later.

3d7ac0d0b1 Note that the example aggregate array_accum is comparable to the now
built-in array_agg.  Per suggestion from Robert Haas.

18004101ac Modify UPDATE/DELETE WHERE CURRENT OF to use the FOR UPDATE infrastructure to
locate the target row, if the cursor was declared with FOR UPDATE or FOR
SHARE.  This approach is more flexible and reliable than digging through the
plan tree; for instance it can cope with join cursors.  But we still provide
the old code for use with non-FOR-UPDATE cursors.  Per gripe from Robert Haas.

32cc9e5533 Reduce contrib/intagg to a thin wrapper around the new core functions
array_agg() and unnest().  We could drop it entirely in the future,
but let's keep it for a release or two as a compatibility assist.

d129255077 Set SQL man pages to be section 7 by default, and only transform them to
another section if required by the platform (instead of the old way of
building them in section "l" and always transforming them to the
platform-specific section).

This speeds up the installation on common platforms, and it avoids some
funny business with the man page tools and build process.

c889ebce0a Implement the basic form of UNNEST, ie unnest(anyarray) returns setof
anyelement.  This lacks the WITH ORDINALITY option, as well as the multiple
input arrays option added in the most recent SQL specs.  But it's still a
pretty useful subset of the spec's functionality, and it is enough to
allow obsoleting contrib/intagg.

2b2fb7d85d Support for man page links, if a man page has more than one refname.
We don't actually use this anywhere, but it might come in handy for dealing
with SELECT/WITH/TABLE.

It works with both the old and the new man page target (for some value of
"works").

f98f6ee064 array_length() function, and for SQL compatibility also cardinality()
function as a special case.

This version still has the suspicious behavior of returning null for an
empty array (rather than zero), but this may need a wholesale revision of
empty array behavior, currently under discussion.

a4917bef0e Add support for input and output of interval values formatted per ISO 8601;
specifically, we can input either the "format with designators" or the
"alternative format", and we can output the former when IntervalStyle is set
to iso_8601.

6462e7b81c Add a --locale switch to createdb, to ease the creation of databases with
different locales.  This is just syntactical sweetener over --lc-collate and
--lc-ctype.  Per discussion.

While at it, properly document --lc-ctype and --lc-collate in SGML docs,
which apparently were forgotten (or purposefully ommited?) when they were
created.

c5451c22e3 Make relhasrules and relhastriggers work like relhasindex, namely we let
VACUUM reset them to false rather than trying to clean 'em up during DROP.

e4718f2c9e Replace pg_class.reltriggers with relhastriggers, which is just a boolean hint
("there might be triggers") rather than an exact count.  This is necessary
catalog infrastructure for the upcoming patch to reduce the strength of
locking needed for trigger addition/removal.  Split out and committed
separately for ease of reviewing/testing.

In passing, also get rid of the unused pg_class columns relukeys, relfkeys,
and relrefs, which haven't been maintained in many years and now have no
chance of ever being maintained (because of wishing to avoid locking).

1d577f5e49 Add a startup check that pg_xlog and pg_xlog/archive_status exist.
If the latter doesn't exist, automatically recreate it.  (We don't do

df7641e25a Add a new GUC variable called "IntervalStyle" that decouples interval output
from DateStyle, and create a new interval style that produces output matching
the SQL standard (at least for interval values that fall within the standard's
restrictions).  IntervalStyle is also used to resolve the conflict between the
standard and traditional Postgres rules for interpreting negative interval
input.

3c2313f481 Change the pgstat logic so that the stats collector writes the stats file only
upon requests from backends, rather than on a fixed 500msec cycle.  (There's
still throttling logic to ensure it writes no more often than once per
500msec, though.)  This should result in a significant reduction in stats file
write traffic in typical scenarios where the stats are demanded only
infrequently.

This approach also means that the former difficulty with changing
stats_temp_directory on-the-fly has gone away, so remove the caution about
that as well as the thrashing we did to minimize the trouble window.

In passing, also fix pgstat_report_stat() so that we will send a stats
message if we have function call stats but not table stats to report;
this fixes a bug in the recent patch to support function-call stats.
