Also applied patch from Lars Stenberg to make callable statements use the form
select * from func() when running against a 7.3 server instead of select func() to allow for set returning functions to be called.

rid of the assumption that sizeof(Oid)==sizeof(int). This is one small
step towards someday supporting 8-byte OIDs. For the moment, it doesn't
do much except get rid of a lot of unsightly casts.

locParam lists can be converted to bitmapsets to speed updating. Also,
replace 'locParam' with 'allParam', which contains all the paramIDs
relevant to the node (i.e., the union of extParam and locParam); this
saves a step during SetChangedParamList() without costing anything
elsewhere.
|
|
Instead of Lists of integers, we now store variable-length bitmap sets.
This should be faster as well as less error-prone.

Instead of grovelling through pg_class to find them, make use of the
handy dandy dependency mechanism: just delete everything that depends
on our temp schema. Unlike the pg_class scan, the dependency mechanism
is smart enough to delete things in an order that doesn't fall foul of
any dependency restrictions. Fixes problem reported by David Heggie:
a temp table with a serial column may cause a backend FATAL exit at
shutdown time, if it chances to try to delete the temp sequence first.

referenced from a subquery. Per example from Stefanos Harhalakis.
|
|
expression accepted by the regex operators, per discussion yesterday.
Along the way, reduce deadlock_timeout from PGC_POSTMASTER to PGC_SIGHUP
category. It is probably best to insist that all backends share the same
setting, but that doesn't mean it has to be frozen at startup.
|
|
per report from Ian Harding.

|
construction 'SETOF type[]' which for some reason was previously
overlooked (you'd have to name the array type directly to make it work).
|
|
(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

|
so that rows can be fetched incrementally. This is enabled by using
setFetchSize()
|
|
and convert pull_agg_clause() into count_agg_clause(), which is a more
efficient way of doing what it's really being used for.
|
|
speeds up some useful real-world cases like
SELECT x, COUNT(*) FROM t GROUP BY x HAVING COUNT(*) > 100.

Curious that gcc doesn't complain about unreferenced static variables.

startup, not in the parser; this allows ALTER DOMAIN to work correctly
with domain constraint operations stored in rules. Rod Taylor;

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%.

Standard says FETCH LAST is after last row, and we don't do that.

either end of subplan results. This prevents misbehavior of cursors
on SELECT DISTINCT ... queries. Per bug report 1-Feb-02.
|
|
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.
|
|
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.

files. Fix it.
|
|
user names. Per recent reports.
|
|
interp pointer. Per report from Gerhard Hintermayer.
|
|
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.

From Andrew Bosma.
|
|
with some amount of cleanliness. I see no need to report the internal
Python name rather than the SQL procedure name in error tracebacks.
|
|
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.

|
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.

From Neil Conway.

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.

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.
|
|
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.
|
|
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.)

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.
|
|
in GUCArrayAdd/GUCArrayDelete. This prevents the multiple-entry bug
exhibited by Frank Lupo 28-Jan-2003.

Set log_min_error_messages to the proper and agreed-upon default, PANIC
(off). (BACKPATCH)
|

Backpatch to 7.3.X.
