The contents of command.c, creatinh.c, define.c, remove.c and rename.c 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>

Partial indexes work again, courtesy of Martijn van Oosterhout. Note: I didn't force an initdb, figuring that one today was enough. However, there is a new function in pg_proc.h, and pg_dump won't be able to dump partial indexes until you add that function.

List *attributeList,
Commit of a *MAJOR* patch from Dan McGuirk <djm@indirect.com> Changes: * Unique index capability works using the syntax 'create unique index'. * Duplicate OID's in the system tables are removed. I put little scripts called 'duplicate_oids' and 'find_oid' in include/catalog that help to find and remove duplicate OID's. I also moved 'unused_oids' from backend/catalog to include/catalog, since it has to be in the same directory as the include files in order to work. * The backend tries converting the name of a function or aggregate to all lowercase if the original name given doesn't work (mostly for compatibility with ODBC). * You can 'SELECT NULL' to your heart's content. * I put my _bt_updateitem fix in instead, which uses _bt_insertonpg so that even if the new key is so big that the page has to be split, everything still works. * All literal references to system catalog OID's have been replaced with references to define'd constants from the catalog header files. * I added a couple of node copy functions. I think this was a preliminary attempt to get rules to work.

bool unique,
The following patch finishes primary key support. Previously, when a field was labelled as a primary key, the system automatically created a unique index on the field. This patch extends it so that the index has the indisprimary field set. You can pull a list of primary keys with the followiing select. SELECT pg_class.relname, pg_attribute.attname FROM pg_class, pg_attribute, pg_index WHERE pg_class.oid = pg_attribute.attrelid AND pg_class.oid = pg_index.indrelid AND pg_index.indkey[0] = pg_attribute.attnum AND pg_index.indisunique = 't'; There is nothing in this patch that modifies the template database to set the indisprimary attribute for system tables. Should they be changed or should we only be concerned with user tables? D'Arcy

bool primary,
Second phase of committing Rod Taylor's pg_depend/pg_constraint patch. 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.

Expr *predicate,
List *rangetable);
First phase of applying Rod Taylor's pg_depend patch. This just adds RESTRICT/CASCADE syntax to the DROP commands that need it, and propagates the behavioral option through the parser to the routines that execute drops. Doesn't do anything useful yet, but I figured I'd commit these changes so I could get out of the parser area while working on the rest.

pg_cast table, and standards-compliant CREATE/DROP CAST commands, plus 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.

Modify sequence state storage to eliminate dangling-pointer problem exemplified by bug #671. Moving the storage to relcache turned out to be a bad idea because relcache might decide to discard the info. Instead, open and close the relcache entry on each sequence operation, and use a record of the current XID to discover whether we already hold AccessShareLock on the sequence.
