Okay, here's my attempt at fixing the problems with parentheses in
subqueries. It passes the normal 'runcheck' tests, and I've tried
a few simple things like
select 1 as foo union (((((select 2))))) order by foo;
There are a few things that it doesn't do that have been talked
about here at least a little:
1) It doesn't allow things like "IN(((select 1)))" -- the select
here has to be at the top level. This is not new.
2) It does NOT preserve the odd syntax I found when I started looking
at this, where a SELECT statement could begin with parentheses. Thus,
(SELECT a from foo) order by a;
fails.
I have preserved the ability, used in the regression tests, to
have a single select statement in what appears to be a RuleActionMulti
(but wasn't -- the parens were part of select_clause syntax).
In my version, this is a special form.
This may cause some discussion: I have differentiated the two kinds
of RuleActionMulti. Perhaps nobody knew there were two kinds, because
I don't think the second form appears in the regression tests. This
one uses square brackets instead of parentheses, but originally was
otherwise the same as the one in parentheses. In this version of
gram.y, the square bracket form treats SELECT statements the same
as the other allowed statements. As discussed before on this list,
psql cannot make sense out of the results of such a thing, but an
application might. And I have designs on just such an application.

Major overhaul of large-object implementation, by Denis Perchine with
kibitzing from Tom Lane. Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'. This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines. LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.

If a field is incompressible ('compressed' data is actually larger than
source, due to addition of header overhead), store it as plain data
rather than pseudo-compressed data. This saves a few microseconds when
