Allow ORDER BY, LIMIT in sub-selects. Fix most (not all) cases where
the grammar did not allow redundant parentheses around sub-selects.
Distinguish LIMIT ALL from LIMIT 0; make the latter behave as one would
expect.
Remove .SECONDARY: target again, because GNU make 3.78.1 will get mighty
confused in src/interfaces/libpq for some reason. Seemingly, different
GNU make versions have several mutually conflicting problems with implicit
rule chains. Words are not sufficient...
Separate CFLAGS_SL and CXXFLAGS_SL, to allow building with C and C++
compilers from different providers. (Especially important since the
C++ compiler that goes with your favourite C compiler might not work.)
Add global .SECONDARY: target to not allow make to delete intermediate
target files in implicit rule chains. That might have been a cool idea
but it seems to be too buggy to work, as it caused spurious recompiles in
several places.

Fix bug reported by bobson: aclinsert3 would delete the 'world' entry
from an ACL list if it had no permissions remaining, which confused
aclcheck terribly. Also clean up code a little.
Add configure check to see whether <string.h> and <strings.h> may both be
included, and then include <strings.h> if so. Several systems already
needed <strings.h> anyway. Some new systems that claim to conform to the
Unix 9x "standard" do not declare str[n]casemp() in string.h, and C99
compilers will not like that.

This is the minimal version of the Darwin support patch from
Bruce Hartzler <bruceh@mail.utexas.edu>. It contains shared library
support, regression test map, and the usual template files. The dynamic
loader is missing, the spin lock code apparently doesn't assemble due to
syntax problems, and semaphores are to be hoped for from Apple.

Change the parser to convert SQL "position" and "substring" syntax to

Add new configure option "--enable-uniconv" that enables automatic

this option requires --enable-multibyte also.
The reason why this is optional is that the feature requires huge

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.

Disallow bits beyond the mask length for CIDR values, per discussion

Re-implement LIMIT/OFFSET as a plan node type, instead of a hack in

From Zoltan Kovacs back in April (sorry for the delay Zoltan!):
I modified the current ODBC driver for
* referential integrity error reporting,
* SELECT in transactions and
* disabling autocommit.
I tested these changes with Borland C++ Builder -> ODBCExpress ->
WinODBC driver (DLL) -> Postgres 7.0beta1 and Borland C++ Builder -> BDE ->
WinODBC driver (DLL) -> Postgres 7.0beta1. The patch is based on snapshot of
22th April (I don't think that someone has modified it since that: Byron
hasn't gave any sign of living for about a month and I didn't find any
comments about the ODBC driver on the list).
