Tom Lane	d67442ccfd	Mop-up some infelicities in new relation lookup handling.	24 years ago
Tom Lane	7863404417	A bunch of changes aimed at reducing backend startup time... ... Improve 'pg_internal.init' relcache entry preload mechanism so that it is safe to use for all system catalogs, and arrange to preload a realistic set of system-catalog entries instead of only the three nailed-in-cache indexes that were formerly loaded this way. Fix mechanism for deleting out-of-date pg_internal.init files: this must be synchronized with transaction commit, not just done at random times within transactions. Drive it off relcache invalidation mechanism so that no special-case tests are needed. Cache additional information in relcache entries for indexes (their pg_index tuples and index-operator OIDs) to eliminate repeated lookups. Also cache index opclass info at the per-opclass level to avoid repeated lookups during relcache load. Generalize 'systable scan' utilities originally developed by Hiroshi, move them into genam.c, use in a number of places where there was formerly ugly code for choosing either heap or index scan. In particular this allows simplification of the logic that prevents infinite recursion between syscache and relcache during startup: we can easily switch to heapscans in relcache.c when and where needed to avoid recursion, so IndexScanOK becomes simpler and does not need any expensive initialization. Eliminate useless opening of a heapscan data structure while doing an indexscan (this saves an mdnblocks call and thus at least one kernel call).	24 years ago
Bruce Momjian	6783b2372e	Another pgindent run. Fixes enum indenting, and improves #endif ... spacing. Also adds space for one-line comments.	24 years ago
Bruce Momjian	b81844b173	pgindent run on all C files. Java run to follow. initdb/regression ... tests pass.	25 years ago
Jan Wieck	8d80b0d980	Statistical system views (yet without the config stuff, but ... it's hard to keep such massive changes in sync with the tree so I need to get it in and work from there now). Jan	25 years ago
Tom Lane	bdadc9bf1c	Remove RelationGetBufferWithBuffer(), which is horribly confused about ... appropriate pin-count manipulation, and instead use ReleaseAndReadBuffer. Make use of the fact that the passed-in buffer (if there is one) must be pinned to avoid grabbing the bufmgr spinlock when we are able to return this same buffer. Eliminate unnecessary 'previous tuple' and 'next tuple' fields of HeapScanDesc and IndexScanDesc, thereby removing a whole lot of bookkeeping from heap_getnext() and related routines.	25 years ago
Bruce Momjian	623bf843d2	Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.	25 years ago
Bruce Momjian	52f77df613	Ye-old pgindent run. Same 4-space tabs.	26 years ago
Tom Lane	34235a295b	Cache fmgr lookup data for index's getnext() function in IndexScanDesc, ... so that the fmgr lookup only has to happen once per index scan and not once per tuple. Seems to save 5% or so of CPU time for an indexscan.	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Tom Lane	9c95f8c9b2	Repair bugs discussed in pghackers thread of 15 May 1999: creation of a ... 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.	26 years ago

Bruce Momjian	7971539020	heap_fetch requires buffer pointer, must be released; heap_getnext ... 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;	28 years ago
