* Fix pgstat_report_waiting() to not dump core if called beforeTom Lane2006-08-28
| | | | | | | | | | pgstat_bestart() has been called; else any lock-block occurring during InitPostgres() is disastrous. I believe this explains recent wasp regression failure; at least it explains the crash I got while trying to duplicate the problem. I also made pgstat_report_activity() safe against the same scenario, just in case. The report_waiting hazard was created by my patch of 19-Aug to include waiting status in pg_stat_activity.
* Partial fix for ecpg's VPATH problems. It compiles and successfullyTom Lane2006-08-28
| | | | | | builds all the files needed for its regression tests, but the tests themselves fail because of diffs in the #line directives output by ecpg itself. Not sure what to do about that.
* Tweak trivial_subqueryscan() to consider a SubqueryScan's targetlistTom Lane2006-08-28
| | | | | | | trivial if it contains either Vars referencing the corresponding subplan columns, or Consts equaling the corresponding subplan columns. This lets the planner eliminate the SubqueryScan in some cases generated by generate_setop_tlist().
* Turn autovacuum on by default. (stats_row_level is also on by default.)Peter Eisentraut2006-08-28
| | | | Threshold and scale factor are cut in half for more aggressive behavior.
* Add new return codes SPI_OK_INSERT_RETURNING etc to the SPI API.Tom Lane2006-08-27
| | | | | | | Fix all the standard PLs to be able to return tuples from FOO_RETURNING statements as well as utility statements that return tuples. Also, fix oversight that SPI_processed wasn't set for a utility statement returning tuples. Per recent discussion.
* Add some notes about why it's not a bug that RI_FKey_check callsTom Lane2006-08-27
| | | | | HeapTupleSatisfiesItself without doing LockBuffer first. This code is a bit fragile, but AFAICS it's not actually broken.
* Add a function GetLockConflicts() to lock.c to report xacts holdingTom Lane2006-08-27
| | | | | | | | | locks that would conflict with a specified lock request, without actually trying to get that lock. Use this instead of the former ad hoc method of doing the first wait step in CREATE INDEX CONCURRENTLY. Fixes problem with undetected deadlock and in many cases will allow the index creation to proceed sooner than it otherwise could've. Per discussion with Greg Stark.
* Move xact.c's partial support for Lists of TransactionIds into pg_list.h.Tom Lane2006-08-27
| | | | Needed because lock.c is now going to use the same type of list.

* Make the server track an 'XID epoch', that is, maintain higher-order bitsTom Lane2006-08-21
| | | | | | | | | of the transaction ID counter. Nothing is done with the epoch except to store it in checkpoint records, but this provides a foundation with which add-on code can pretend that XIDs never wrap around. This is a severely trimmed and rewritten version of the xxid patch submitted by Marko Kreen. Per discussion, the epoch counter seems the only part of xxid that really needs to be in the core server.

* Fixed a few memory leaks. One indeed was part of a loop.Michael Meskes2006-08-21

* Fix all known problems with pg_dump's handling of serial sequencesTom Lane2006-08-21
| | | | | | | | | | | | | | | | | | | | | by abandoning the idea that it should say SERIAL in the dump. Instead, dump serial sequences and column defaults just like regular ones. Add a new backend command ALTER SEQUENCE OWNED BY to let pg_dump recreate the sequence-to-column dependency that was formerly created "behind the scenes" by SERIAL. This restores SERIAL to being truly "just a macro" consisting of component operations that can be stated explicitly in SQL. Furthermore, the new command allows sequence ownership to be reassigned, so that old mistakes can be cleaned up. Also, downgrade the OWNED-BY dependency from INTERNAL to AUTO, since there is no longer any very compelling argument why the sequence couldn't be dropped while keeping the column. (This forces initdb, to be sure the right kinds of dependencies are in there.) Along the way, add checks to prevent ALTER OWNER or SET SCHEMA on an owned sequence; you can now only do this indirectly by changing the owning table's owner or schema. This is an oversight in previous releases, but probably not worth back-patching.
* Fix DROP OWNED BY to correctly consider the implicitly-deleted objects list forAlvaro Herrera2006-08-20
| | | | | | | | | | | | | each object to be deleted, instead of the previous hack that just skipped INTERNAL dependencies, which didn't really work. Per report from Tom Lane. To do this, introduce a new performMultipleDeletions entry point in dependency.c to delete multiple objects at once. The dependency code then has the responsability of tracking INTERNAL and AUTO dependencies as needed. Along the way, change ObjectAddresses so that we can allocate an ObjectAddress list from outside dependency.c and not have to export the internal representation.
* Fixed a few trivial memory leaks reported by Coverity just to test my setup.Michael Meskes2006-08-20
