* Fix VACUUM so that it can use pages as move targets even if they do notTom Lane2001-06-29
| | | | | | | | | have any newly-dead tuples on them. This is a longstanding deficiency that prevents VACUUM from compacting a file as much as one would expect. Change requires fixing repair_frag to not assume that fraged_pages is a subset of vacuum_pages. Also make some further cleanups of places that assumed page numbers fit in int and tuple counts fit in uint32.

Make some gestures towards allowing number of blocks in a relation to be BlockNumber, ie, unsigned int, rather than signed int. (I doubt I got all the places that are sloppy about it, yet.) On the way, replace the hardwired NLOCKS_PER_XACT fudge factor with a GUC variable.

Split out selectivity support functions from builtins.h into a new header file selfuncs.h, so as to reduce the number of header files builtins.h must depend on. Fix a few missing inclusions exposed thereby. From Joe Conway, with some kibitzing from Tom Lane.

| | | | | | | | | | a new postmaster child process. This should eliminate problems with authentication blocking (e.g., ident, SSL init) and also reduce problems with the accept queue filling up under heavy load. The option to send elog output to a different file per backend (postgres -o) has been disabled for now because the initialization would have to happen in a different order and it's not clear we want to keep this anyway.

* Clean up some longstanding problems in shared-cache invalidation.Tom Lane2001-06-19
| | | | | | | | | | | | SI messages now include the relevant database OID, so that operations in one database do not cause useless cache flushes in backends attached to other databases. Declare SI messages properly using a union, to eliminate the former assumption that Oid is the same size as int or Index. Rewrite the nearly-unreadable code in inval.c, and document it better. Arrange for catcache flushes at end of command/transaction to happen before relcache flushes do --- this avoids loading a new tuple into the catcache while setting up new relcache entry, only to have it be flushed again immediately.

* Do some restructuring to improve performance of the catcaches. TeachTom Lane2001-06-18
| | | | | | | | | | | | | | | | | CatalogCacheFlushRelation (formerly called SystemCacheRelationFlushed) how to distinguish tuples it should flush from those it needn't; this means a relcache flush event now only removes the catcache entries it ought to, rather than zapping the caches completely as it used to. Testing with the regression tests indicates that this considerably improves the lifespan of catcache entries. Also, rearrange catcache data structures so that the limit on number of cached tuples applies globally across all the catcaches, rather than being per-catcache. It was a little silly to have the same size limit on both, say, pg_attribute caches and pg_am caches (there being only four possible rows in the latter...). Doing LRU removal across all the caches instead of locally in each one should reduce cache reload traffic in the more heavily used caches and improve the efficiency of cache memory use.
* Keep the list of to-be-NOTIFYed names in a plain List palloc'd inTom Lane2001-06-17
| | | | | | | TopTransactionContext, rather than using Dllist. This simplifies and speeds up the code, and eliminates a former risk of coredump when out of memory (since the old code didn't bother to check for malloc failure). It also moves us one step closer to retiring Dllist...

* Tweak startup sequence so that running out of PROC array slots isTom Lane2001-06-16
| | | | | | | | | | detected sooner in backend startup, and is treated as an expected error (it gives 'Sorry, too many clients already' now). This allows us not to have to enforce the MaxBackends limit exactly in the postmaster. Also, remove ProcRemove() and fold its functionality into ProcKill(). There's no good reason for a backend not to be responsible for removing its PROC entry, and there are lots of good reasons for the postmaster not to be touching shared-memory data structures.
* It turns out that the relcache thinks it can distinguish differentTom Lane2001-06-16
| | | | | | | rules and triggers by OID. So, even though we have no cross-references in the system catalogs to pg_rewrite.oid or pg_trigger.oid, we'd better have unique indexes on them. Put back pg_rewrite_oid_index, which I mistakenly removed a few days ago, and add pg_trigger_oid_index.

* has_table_privilege functions from Joe Conway (with some kibitzing fromTom Lane2001-06-14
| | | | | | Tom Lane). For the moment, only the OID/name variants are provided. I didn't force initdb, but the additions to the 'privileges' regress test won't pass until you do one.
* Allow a non-superuser database owner to vacuum all tables in hisTom Lane2001-06-13
| | | | | | | database, including system catalogs (but not the shared catalogs, since they don't really belong to his database). This is per recent mailing list discussion. Clean up some other code that also checks for database ownerness by introducing a test function is_dbadmin().
* Attached is a patch adding following functions:Bruce Momjian2001-06-13

* Extend GUC concepts of parse_hook and assign_hook to all four supportedTom Lane2001-06-12
| | | | | | | | | | | | datatypes, not only strings. parse_hook is useless for bool, I suppose, but it seems possibly useful for int and double to apply variable-specific constraints that are more complex than simple range limits. assign_hook is definitely useful for all datatypes --- we need it right now for bool to support date cache reset when changing Australian timezone rule setting. Also, clean up some residual problems with the reset all/show all patch, including memory leaks and mistaken reset of PostPortNumber. It seems best that RESET ALL not touch variables that don't have SUSET or USERSET context.

There are now both Text and Name variants, and the regression test support is rolled into the patch. Note that to be complete wrt Name based variants, there are now 12 user visible versions of has_table_privilege: has_table_privilege(Text usename, Text relname, Text priv_type) has_table_privilege(Text usename, Name relname, Text priv_type) has_table_privilege(Name usename, Text relname, Text priv_type) has_table_privilege(Name usename, Name relname, Text priv_type) has_table_privilege(Text relname, Text priv_type) /* assumes current_user */ has_table_privilege(Name relname, Text priv_type) /* assumes current_user */ has_table_privilege(Text usename, Oid reloid, Text priv_type) has_table_privilege(Name usename, Oid reloid, Text priv_type) has_table_privilege(Oid reloid, Text priv_type) /* assumes current_user */ has_table_privilege(Oid usesysid, Text relname, Text priv_type) has_table_privilege(Oid usesysid, Name relname, Text priv_type) has_table_privilege(Oid usesysid, Oid reloid, Text priv_type) For the Text based inputs, a new internal function, get_Name is used (shamelessly copied from get_seq_name in sequence.c) to downcase if not quoted, or remove quotes if quoted, and truncate. I also added a few test cases for the downcasing, quote removal, and Name based variants to the regression test. Joe Conway
* Clean up various to-do items associated with system indexes:Tom Lane2001-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pg_database now has unique indexes on oid and on datname. pg_shadow now has unique indexes on usename and on usesysid. pg_am now has unique index on oid. pg_opclass now has unique index on oid. pg_amproc now has unique index on amid+amopclaid+amprocnum. Remove pg_rewrite's unnecessary index on oid, delete unused RULEOID syscache. Remove index on pg_listener and associated syscache for performance reasons (caching rows that are certain to change before you need 'em again is rather pointless). Change pg_attrdef's nonunique index on adrelid into a unique index on adrelid+adnum. Fix various incorrect settings of pg_class.relisshared, make that the primary reference point for whether a relation is shared or not. IsSharedSystemRelationName() is now only consulted to initialize relisshared during initial creation of tables and indexes. In theory we might now support shared user relations, though it's not clear how one would get entries for them into pg_class &etc of multiple databases. Fix recently reported bug that pg_attribute rows created for an index all have the same OID. (Proof that non-unique OID doesn't matter unless it's actually used to do lookups ;-)) There's no need to treat pg_trigger, pg_attrdef, pg_relcheck as bootstrap relations. Convert them into plain system catalogs without hardwired entries in pg_class and friends. Unify global.bki and template1.bki into a single init script postgres.bki, since the alleged distinction between them was misleading and pointless. Not to mention that it didn't work for setting up indexes on shared system relations. Rationalize locking of pg_shadow, pg_group, pg_attrdef (no need to use AccessExclusiveLock where ExclusiveLock or even RowExclusiveLock will do). Also, hold locks until transaction commit where necessary.
