pghackers discussion of 5-Jan-2000. The amopselect and amopnpages estimators are gone, and in their place is a per-AM amcostestimate procedure (linked to from pg_am, not pg_amop).

relcache entry no longer leaks a small amount of memory. index_endscan now releases all the memory acquired by index_beginscan, so callers of it should NOT pfree the scan descriptor anymore.

additional argument specifying the kind of lock to acquire/release (or 'NoLock' to do no lock processing). Ensure that all relations are locked with some appropriate lock level before being examined --- this ensures that relevant shared-inval messages have been processed and should prevent problems caused by concurrent VACUUM. Fix several bugs having to do with mismatched increment/decrement of relation ref count and mismatched heap_open/close (which amounts to the same thing). A bogus ref count on a relation doesn't matter much *unless* a SI Inval message happens to arrive at the wrong time, which is probably why we got away with this sloppiness for so long. Repair missing grab of AccessExclusiveLock in DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi. Recommend 'make clean all' after pulling this update; I modified the Relation struct layout slightly. Will post further discussion to pghackers list shortly.

for against a just updated CVS tree. It contains Partial new rewrite system that handles subselects, view aggregate columns, insert into select from view, updates with set col = view-value and select rules restriction to view definition. Updates for rule/view backparsing utility functions to handle subselects correct. New system views pg_tables and pg_indexes (where you can see the complete index definition in the latter one). Enabling array references on query parameters. Bugfix for functional index. Little changes to system views pg_rules and pg_views. The rule system isn't a release-stopper any longer. But another stopper is that I don't know if the latest changes to PL/pgSQL (not already in CVS) made it compile on AIX. Still wait for some response from Dave. Jan

no longer returns buffer pointer, can be gotten from scan; descriptor; bootstrap can create multi-key indexes; pg_procname index now is multi-key index; oidint2, oidint4, oidname are gone (must be removed from regression tests); use System Cache rather than sequential scan in many places; heap_modifytuple no longer takes buffer parameter; remove unused buffer parameter in a few other functions; oid8 is not index-able; remove some use of single-character variable names; cleanup Buffer variables usage and scan descriptor looping; cleaned up allocation and freeing of tuples; 18k lines of diff;

As an example I sent a bug-report on 26 Nov to tell that the fix included below is necessary to compile pg95-current on Ultrix with Digital's standard C compiler c89. In fact I think that this fix is needed for any C compiler sticking very close the standard, see my discussion in the original bug report. Erik Bertelsen

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.
