* Add a bunch of pseudo-types to replace the behavior formerly associatedTom Lane2002-08-22
| | | | | | with OPAQUE, as per recent pghackers discussion. I still want to do some more work on the 'cstring' pseudo-type, but I'm going to commit the bulk of the changes now before the tree starts shifting under me ...
* Create/drop cast now requires ownership of at least one of the types.Peter Eisentraut2002-08-11

* Restructure system-catalog index updating logic. Instead of havingTom Lane2002-08-05
| | | | | | | | | hardwired lists of index names for each catalog, use the relcache's mechanism for caching lists of OIDs of indexes of any table. This reduces the common case of updating system catalog indexes to a single line, makes it much easier to add a new system index (in fact, you can now do so on-the-fly if you want to), and as a nice side benefit improves performance a little. Per recent pghackers discussion.

For pg_type, there is no warning (yet) because pg_dump scripts still contain these attributes. Also remove new but already obsolete spellings isVolatile, isStable, isImmutable in WITH clause. (Use new syntax instead.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bitmap, if present). Per Tom Lane's suggestion the information whether a tuple has an oid or not is carried in the tuple descriptor. For debugging reasons tdhasoid is of type char, not bool. There are predefined values for WITHOID, WITHOUTOID and UNDEFOID. This patch has been generated against a cvs snapshot from last week and I don't expect it to apply cleanly to current sources. While I post it here for public review, I'm working on a new version against a current snapshot. (There's been heavy activity recently; hope to catch up some day ...) This is a long patch; if it is too hard to swallow, I can provide it in smaller pieces: Part 1: Accessor macros Part 2: tdhasoid in TupDesc Part 3: Regression test Part 4: Parameter withoid to heap_addheader Part 5: Eliminate t_oid from HeapTupleHeader Part 2 is the most hairy part because of changes in the executor and even in the parser; the other parts are straightforward. Up to part 4 the patched postmaster stays binary compatible to databases created with an unpatched version. Part 5 is small (100 lines) and finally breaks compatibility. Manfred Koizar
* pg_cast table, and standards-compliant CREATE/DROP CAST commands, plusPeter Eisentraut2002-07-18
| | | | | | | | | | | extension to create binary compatible casts. Includes dependency tracking as well. pg_proc.proimplicit is now defunct, but will be removed in a separate commit. pg_dump provides a migration path from the previous scheme to declare casts. Dumping binary compatible casts is currently impossible, though.
* Second phase of committing Rod Taylor's pg_depend/pg_constraint patch.Tom Lane2002-07-12
| | | | | | | | | | | | pg_relcheck is gone; CHECK, UNIQUE, PRIMARY KEY, and FOREIGN KEY constraints all have real live entries in pg_constraint. pg_depend exists, and RESTRICT/CASCADE options work on most kinds of DROP; however, pg_depend is not yet very well populated with dependencies. (Most of the ones that are present at this point just replace formerly hardwired associations, such as the implicit drop of a relation's pg_type entry when the relation is dropped.) Need to add more logic to create dependency entries, improve pg_dump to dump constraints in place of indexes and triggers, and add some regression tests.

* Add optional "validator" function to languages that can validate thePeter Eisentraut2002-05-22
| | | | | | | | | | | | function body (and other properties) as a function in the language is created. This generalizes ad hoc code that already existed for the built-in languages. The validation now happens after the pg_proc tuple of the new function is created, so it is possible to define recursive SQL functions. Add some regression test cases that cover bogus function definition attempts.
* Allow functions to be executed with the privileges of the function owner.Peter Eisentraut2002-05-18

* Restructure aclcheck error reporting to make permission-failureTom Lane2002-04-27
| | | | | | | messages more uniform and internationalizable: the global array aclcheck_error_strings[] is gone in favor of a subroutine aclcheck_error(). Partial implementation of namespace-related permission checks --- not all done yet.
* Restructure AclItem representation so that we can have more than eightTom Lane2002-04-21
| | | | | | | | | different privilege bits (might as well make use of the space we were wasting on padding). EXECUTE and USAGE bits for procedures, languages now are separate privileges instead of being overlaid on SELECT. Add privileges for namespaces and databases. The GRANT and REVOKE commands work for these object types, but we don't actually enforce the privileges yet...
* The contents of command.c, creatinh.c, define.c, remove.c and rename.cTom Lane2002-04-15
have been divided according to the type of object manipulated - so ALTER TABLE code is in tablecmds.c, aggregate commands in aggregatecmds.c and so on. A few common support routines remain in define.c (prototypes in src/include/commands/defrem.h). No code has been changed except for includes to reflect the new files. The prototypes for aggregatecmds.c, functioncmds.c, operatorcmds.c, and typecmds.c remain in src/include/commands/defrem.h. From John Gray <jgray@azuli.co.uk>
