* This patch fixes an error in the usage message for 'clusterdb', andBruce Momjian2003-02-13
| | | | | | | makes a few editorial changes to the documentation. Neil Conway
* This trivial patch removes the usage of some old statistics code that noBruce Momjian2003-02-13
| | | | | | | | | longer works -- IncrHeapAccessStat() didn't actually *do* anything anymore, so no reason to keep it around AFAICS. I also fixed a grammatical error in a comment. Neil Conway
* Adds in NO MAXVALUE and NO MINVALUE options for create sequence per 200XBruce Momjian2003-02-13

* The "random" regression test uses a function called oidrand(), whichBruce Momjian2003-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | takes two parameters, an OID x and an integer y, and returns "true" with probability 1/y (the OID argument is ignored). This can be useful -- for example, it can be used to select a random sampling of the rows in a table (which is what the "random" regression test uses it for). This patch removes that function, because it was old and messy. The old function had the following problems: - it was undocumented - it was poorly named - it was designed to workaround an optimizer bug that no longer exists (the OID argument is to ensure that the optimizer won't optimize away calls to the function; AFAIK marking the function as 'volatile' suffices nowadays) - it used a different random-number generation technique than the other PSRNG-related functions in the backend do (it called random() like they do, but it had its own logic for setting a set and deciding when to reseed the RNG). Ok, this patch removes oidrand(), oidsrand(), and userfntest(), and improves the SGML docs a little bit (un-commenting the setseed() documentation). Neil Conway

* This patch makes pg_get_constraintdef support UNIQUE, PRIMARY KEY andBruce Momjian2003-02-13
| | | | | | | | | | | CHECK constraints. There are apparently no other types of constraint in pg_constraint, so now all bases are covered. Also, this patch assumes that consrc for a CHECK constraint is always bracketed so that it's not necessary to add extra brackets. Christopher Kings-Lynne

The attached patch covers the first of the two proposals, i.e. restricting the target list to only one set returning function. It compiles cleanly, and passes all regression tests. If there are no objections, please apply. Any suggestions on where this should be documented (other than maybe sql-select)? Thanks, Joe p.s. Here's what the previous example now looks like: CREATE TABLE bar(f1 int, f2 text, f3 int); INSERT INTO bar VALUES(1, 'Hello', 42); INSERT INTO bar VALUES(2, 'Happy', 45); CREATE TABLE foo(a int, b text); INSERT INTO foo VALUES(42, 'World'); INSERT INTO foo VALUES(42, 'Everyone'); INSERT INTO foo VALUES(45, 'Birthday'); INSERT INTO foo VALUES(45, 'New Year'); CREATE TABLE foo2(a int, b text); INSERT INTO foo2 VALUES(42, '!!!!'); INSERT INTO foo2 VALUES(42, '????'); INSERT INTO foo2 VALUES(42, '####'); INSERT INTO foo2 VALUES(45, '$$$$'); CREATE OR REPLACE FUNCTION getfoo(int) RETURNS SETOF text AS ' SELECT b FROM foo WHERE a = $1 ' language 'sql'; CREATE OR REPLACE FUNCTION getfoo2(int) RETURNS SETOF text AS ' SELECT b FROM foo2 WHERE a = $1 ' language 'sql'; regression=# SELECT f1, f2, getfoo(f3) AS f4 FROM bar; f1 | f2 | f4 ----+-------+---------- 1 | Hello | World 1 | Hello | Everyone 2 | Happy | Birthday 2 | Happy | New Year (4 rows) regression=# SELECT f1, f2, getfoo(f3) AS f4, getfoo2(f3) AS f5 FROM bar; ERROR: Only one target list entry may return a set result Joe Conway

* Use a varno not chosen at random for dummy variables in the top-levelTom Lane2003-02-11
| | | | | | | | | targetlist of a set-operation tree. I'm not sure that this solution will really stand the test of time --- perhaps we need to make a special RTE for such vars to refer to. But this quick hack fixes Brandon Craig Rhodes' complaint of 10-Feb-02 about EXCEPT in CREATE RULE, while not changing any behavior in the better-tested cases where leftmostRTI is one anyway.
* Fix thinko in new logic about pushing down non-nullability constraints:Tom Lane2003-02-10
| | | | | | constraints appearing in outer-join qualification clauses are restricted as to when and where they can be pushed down. Add regression test to catch future errors in this area.
* Add code to show join rule (for outer and IN joins) in join type name.Tom Lane2003-02-10
|
* Get rid of last few vestiges of parsetree dependency on grammar tokenTom Lane2003-02-10
| | | | | | codes, per discussion from last March. parse.h should now be included *only* by gram.y, scan.l, keywords.c, parser.c. This prevents surprising misbehavior after seemingly-trivial grammar adjustments.
* Detect case where an outer join can be reduced to a plain inner joinTom Lane2003-02-09
| | | | | because there are WHERE clauses that will reject the null-extended rows. Per suggestion from Brandon Craig Rhodes, 19-Nov-02.

* Better error message on character set mismatches during conversion to unicode.Barry Lind2003-02-09
| | | | | | | | | | 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. Modified Files: jdbc/org/postgresql/errors.properties jdbc/org/postgresql/core/Encoding.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Statement.java
* Create a distinction between Lists of integers and Lists of OIDs, to getTom Lane2003-02-09
| | | | | | 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.
* Remove bogus comment (too freely copied & pasted).Tom Lane2003-02-09

* Make further use of new bitmapset code: executor's chgParam, extParam,Tom Lane2003-02-09
| | | | | | | | 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.
* Replace planner's representation of relation sets, per pghackers discussion.Tom Lane2003-02-08
| | | | | Instead of Lists of integers, we now store variable-length bitmap sets. This should be faster as well as less error-prone.

* Revise mechanism for getting rid of temp tables at backend shutdown.Tom Lane2003-02-07
| | | | | | | | | | 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.
* Make flatten_join_alias_vars() do the right thing when expanding an aliasTom Lane2003-02-06
| | | | referenced from a subquery. Per example from Stefanos Harhalakis.
* Create a GUC variable REGEX_FLAVOR to control the type of regularTom Lane2003-02-06
| | | | | | | | 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.
* Fix core dump when pltcl_elog is called with wrong number of parameters,Tom Lane2003-02-06
| | | | per report from Ian Harding.
* Allow qualified type names in CREATE CAST, DROP CAST. Also allow theTom Lane2003-02-05
| | | | | construction 'SETOF type[]' which for some reason was previously overlooked (you'd have to name the array type directly to make it work).
* Replace regular expression package with Henry Spencer's latest versionTom Lane2003-02-05
| | | | | | | (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.

* Patch from Nic Ferrier to add support for result sets being cursor basedBarry Lind2003-02-04
| | | | | so that rows can be fetched incrementally. This is enabled by using setFetchSize()
* Minor code cleanup: remove no-longer-useful pull_subplans() function,Tom Lane2003-02-04
| | | | | and convert pull_agg_clause() into count_agg_clause(), which is a more efficient way of doing what it's really being used for.
* Detect duplicate aggregate calls and evaluate only one copy. ThisTom Lane2003-02-04
| | | | | speeds up some useful real-world cases like SELECT x, COUNT(*) FROM t GROUP BY x HAVING COUNT(*) > 100.
* #ifdef out stuff that shouldn't be compiled when not USE_SSL.Tom Lane2003-02-03
| | | | Curious that gcc doesn't complain about unreferenced static variables.
* Determine the set of constraints applied to a domain at executorTom Lane2003-02-03
| | | | | | startup, not in the parser; this allows ALTER DOMAIN to work correctly with domain constraint operations stored in rules. Rod Taylor; code review by Tom Lane.

* Tweak planner and executor to avoid doing ExecProject() in table scanTom Lane2003-02-03
| | | | | | | | 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%.

* Change MOVE LAST to MOVE ALL.Bruce Momjian2003-02-03

* Fix nodeUnique to behave correctly when reversing direction after reachingTom Lane2003-02-02
| | | | | either end of subplan results. This prevents misbehavior of cursors on SELECT DISTINCT ... queries. Per bug report 1-Feb-02.
* Remove restriction that cast functions cannot be volatile. ThisTom Lane2003-02-01
| | | | | | 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.
