* Som improve page split in multicolumn GiST index.Teodor Sigaev2006-05-29
| | | | | | If user picksplit on n-th column generate equals left and right unions then it calls picksplit on n+1-th column.
* * Add support NULL to GiST.Teodor Sigaev2006-05-24
| | | | | | | | * some refactoring and simplify code int gistutil.c and gist.c * now in some cases it can be called used-defined picksplit method for non-first column in index, but here is a place to do more. * small fix of docs related to support NULL.
* Simplify gistSplit() and some refactoring related code.Teodor Sigaev2006-05-19

* Reduce size of critial section during vacuum full, criticalTeodor Sigaev2006-05-17
| | | | | | | | sections now isn't nested. All user-defined functions now is called outside critsections. Small improvements in WAL protocol. TODO: improve XLOG replay
* Reduce size of critical section and remove call of user-defined functions inTeodor Sigaev2006-05-10
| | | | | | insertion and deletion, modify gistSplit() to do not use buffers. TODO: gistvacuumcleanup and XLOG
* Update copyright for 2006. Update scripts.Bruce Momjian2006-03-05

* Re-run pgindent, fixing a problem where comment lines after a blankBruce Momjian2005-11-22
| | | | | | | | | comment line where output as too long, and update typedefs for /lib directory. Also fix case where identifiers were used as variable names in the backend, but as typedefs in ecpg (favor the backend for indenting). Backpatch to 8.1.X.
* Add simple sanity checks on newly-read pages to GiST, too.Tom Lane2005-11-06

* Bug fixes for GiST crash recovery.Teodor Sigaev2005-06-30
| | | | | | - add forgotten check of lsn for insert completion - remove level of pages: hard to check in recovery - some cleanups
* Code cleanup. gistfillbuffer accepts InvalidOffsetNumber.Teodor Sigaev2005-06-28

* Concurrency for GiSTTeodor Sigaev2005-06-27
| | | | | | | | | | | | | | | | | | - full concurrency for insert/update/select/vacuum: - select and vacuum never locks more than one page simultaneously - select (gettuple) hasn't any lock across it's calls - insert never locks more than two page simultaneously: - during search of leaf to insert it locks only one page simultaneously - while walk upward to the root it locked only parent (may be non-direct parent) and child. One of them X-lock, another may be S- or X-lock - 'vacuum full' locks index - improve gistgetmulti - simplify XLOG records Fix bug in index_beginscan_internal: LockRelation may clean rd_aminfo structure, so move GET_REL_PROCEDURE after LockRelation
* 1. full functional WAL for GiSTTeodor Sigaev2005-06-20
| | | | | | | | | | | 2. improve vacuum for gist - use FSM - full vacuum: - reforms parent tuple if it's needed ( tuples was deleted on child page or parent tuple remains invalid after crash recovery ) - truncate index file if possible 3. fixes bugs and mistakes
* WAL for GiST. It work for online backup and so on, but onTeodor Sigaev2005-06-14
recovery after crash (power loss etc) it may say that it can't restore index and index should be reindexed. Some refactoring code.
