e24977f3a4 Allow qualified type names in CREATE CAST, DROP CAST. Also allow the
construction 'SETOF type[]' which for some reason was previously
overlooked (you'd have to name the array type directly to make it work).

7bcc6d98fb Replace regular expression package with Henry Spencer's latest version
(extracted from Tcl 8.4.1 release, as Henry still hasn't got round to
making it a separate library).  This solves a performance problem for
multibyte, as well as upgrading our regexp support to match recent Tcl
and nearly match recent Perl.

and the other fixes a NPE in Statement.toString() under some circumstances.
The second patch was originally submitted by Oliver Jowett and updated by Kris

16a30346c8 Patch from Nic Ferrier to add support for result sets being cursor based
so that rows can be fetched incrementally.  This is enabled by using

2d1f940542 Minor code cleanup: remove no-longer-useful pull_subplans() function,
and convert pull_agg_clause() into count_agg_clause(), which is a more
efficient way of doing what it's really being used for.

85caf1784a Detect duplicate aggregate calls and evaluate only one copy. This
speeds up some useful real-world cases like
SELECT x, COUNT(*) FROM t GROUP BY x HAVING COUNT(*) > 100.

ef5842b5f7 #ifdef out stuff that shouldn't be compiled when not USE_SSL.
Curious that gcc doesn't complain about unreferenced static variables.

3752e85bad Determine the set of constraints applied to a domain at executor
startup, not in the parser; this allows ALTER DOMAIN to work correctly
with domain constraint operations stored in rules.  Rod Taylor;

4cff59d8d5 Tweak planner and executor to avoid doing ExecProject() in table scan
nodes where it's not really necessary.  In many cases where the scan node
is not the topmost plan node (eg, joins, aggregation), it's possible to
just return the table tuple directly instead of generating an intermediate
projection tuple.  In preliminary testing, this reduced the CPU time
needed for 'SELECT COUNT(*) FROM foo' by about 10%.

967e8a37ab Fix nodeUnique to behave correctly when reversing direction after reaching
either end of subplan results.  This prevents misbehavior of cursors
on SELECT DISTINCT ... queries.  Per bug report 1-Feb-02.

6ba8af9d5d Remove restriction that cast functions cannot be volatile. This
restriction was debatable to begin with, but it has now become obvious
that it breaks forward-porting of user-defined types; contrib/lo being
the most salient example.

e0a1ee2053 Cleaner solution to the problem of loading pre-7.3 dumps containing
columns of type lo (see contrib/lo).  Rather than hacking the function
definitions on-the-fly, just modify the queries issued by FixupBlobRefs
so that they work even if CREATE CAST hasn't been issued.

032235cafe Apply ljb's patch to prevent both memory leak and core dump during
connection shutdown.  This is a grotty workaround for a Tcl bug, but
said bug has been there long enough that I'm not holding my breath
for a real fix.  Per discussions and testing from ljb and g.hintermayer.

6f49703f0e Clean up plpython error reporting so that its regression test passes
with some amount of cleanliness.  I see no need to report the internal
Python name rather than the SQL procedure name in error tracebacks.

9d00798720 Tweak bison build rules so that we get the same error messages from
bison 1.875 and later as we did from earlier bison releases.  Eventually
we will probably want to adopt the newer message spelling ... but not yet.
Per recent discussion on pgpatches.
Note: I didn't change the build rules for bootstrap, ecpg, or plpgsql
grammars, since these do not affect regression test results.

bd96dd1184 Allow a time zone to be specified (and silently ignored) in the input
for type 'time without time zone', as we already did for type
'timestamp without time zone'.  This patch was proposed by Tom Lockhart
on 7-Nov-02, but he never got around to applying it.  Adjust regression
tests and documentation to match.

26f56131ae SPI_exec shouldn't return SPI_OK_SELECT if it hasn't actually returned
a tuple table.  Fixes core dump in pltcl (and probably other PLs) when
executing a query rewritten by a rule.  Per bug report from Wolfgang Walter.

5fdb142f16 Tweak ArrayCount() to forestall possible access to temp[-1]. Problem
cannot actually happen at present because ArrayCount() is only called
on strings beginning with '{', but seems best to prevent it going forward.
Per report from Yichen Xie.

3cb282f3e6 Guard against array overrun, per report from Yichen Xie. This case
can only occur if the constant DEFAULT_CLIENT_AUTHSVC is given a bogus
value, so it doesn't seem worth back-patching, but I'll fix it in HEAD.

23b8a0ce61 Repair array subscript overrun identified by Yichen Xie. Reduce the
value of MAX_TIME_PRECISION in floating-point-timestamp-storage case
from 13 to 10, which is as much as time_out is actually willing to print.
(The alternative of increasing the number of digits we are willing to
print looks risky; we might find ourselves printing roundoff garbage.)

2e46b762eb Extend join-selectivity API (oprjoin interface) so that join type is
passed to join selectivity estimators.  Make use of this in eqjoinsel
to derive non-bogus selectivity for IN clauses.  Further tweaking of
cost estimation for IN.
initdb forced because of pg_proc.h changes.

955a1f81a7 Factor out the code that detects the long long int snprintf format into a
separate macro.  Also add support for %I64d which is the way on Windows.

The code that checks for the 64-bit int type now gives more reasonable
results when cross-compiling: In that case we just take the compiler's
information and trust that the arithmetic works.  Disabling int64 is too
pessimistic.
