Switch the planner over to treating qualifications of a JOIN_SEMI join as
though it is an inner rather than outer join type. This essentially means
that we don't bother to separate "pushed down" qual conditions from actual
join quals at a semijoin plan node; which is okay because the restrictions of
SQL syntax make it impossible to have a pushed-down qual that references the
inner side of a semijoin. This allows noticeably better optimization of
IN/EXISTS cases than we had before, since the equivalence-class machinery can
now use those quals. Also fix a couple of other mistakes that had essentially
disabled the ability to unique-ify the inner relation and then join it to just
a subset of the left-hand relations. An example case using the regression
database is
select * from tenk1 a, tenk1 b
where (a.unique1,b.unique2) in (select unique1,unique2 from tenk1 c);

Add an explicit caution about how to use pg_do_encoding_conversion with
non-null-terminated input. Per discussion with ITAGAKI Takahiro.

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.

Fix bugs in sqlchar_to_unicode and unicode_to_sqlchar: both were measuring
the length of a UTF8 character with pg_mblen (wrong if DB encoding isn't
UTF8), and the latter was blithely assuming that a static buffer would somehow
revert to all zeroes for each use.

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.

pg_do_encoding_conversion cannot return NULL (at least not unless the input
is NULL), so remove some useless tests for the case.

Fix old bug in contrib/sslinfo: X509_NAME_to_text freed the BIO_s_mem buffer
it was using too soon. In a situation where pg_do_encoding_conversion is
a no-op, this led to garbage data returned.
In HEAD, also modify the code that's ensuring null termination to make it
a tad more obvious what's happening.

Make relhasrules and relhastriggers work like relhasindex, namely we let
VACUUM reset them to false rather than trying to clean 'em up during DROP.
Tom Lane [Sun, 9 Nov 2008 21:24:33 +0000 (21:24 +0000)]
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).

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.

Add some more citext test cases, per David Wheeler. Also remove the
