*	Som improve page split in multicolumn GiST index.	Teodor Sigaev	2006-05-29
\| \| \| \| \| \|	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 Sigaev	2006-05-24
\| \| \| \| \| \| \| \|	* 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 Sigaev	2006-05-19

*	Reduce size of critial section during vacuum full, critical	Teodor Sigaev	2006-05-17
\| \| \| \| \| \| \| \|	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 in	Teodor Sigaev	2006-05-10
\| \| \| \| \| \|	insertion and deletion, modify gistSplit() to do not use buffers. TODO: gistvacuumcleanup and XLOG
*	Improve gist XLOG code to follow the coding rules needed to prevent	Tom Lane	2006-03-30
\| \| \| \| \| \| \|	torn-page problems. This introduces some issues of its own, mainly that there are now some critical sections of unreasonably broad scope, but it's a step forward anyway. Further cleanup will require some code refactoring that I'd prefer to get Oleg and Teodor involved in.
*	Arrange to emit a description of the current XLOG record as error context	Tom Lane	2006-03-24
\| \| \| \| \| \| \| \| \|	when an error occurs during xlog replay. Also, replace the former risky 'write into a fixed-size buffer with no overflow detection' API for XLOG record description routines; use an expansible StringInfo instead. (The latter accounts for most of the patch bulk.) Qingqing Zhou
*	Update copyright for 2006. Update scripts.	Bruce Momjian	2006-03-05

*	Add simple sanity checks on newly-read pages to GiST, too.	Tom Lane	2005-11-06
\|
*	Standard pgindent run for 8.1.	Bruce Momjian	2005-10-15

*	Bug fixes for GiST crash recovery.	Teodor Sigaev	2005-06-30
\| \| \| \| \| \|	- add forgotten check of lsn for insert completion - remove level of pages: hard to check in recovery - some cleanups
*	Concurrency for GiST	Teodor Sigaev	2005-06-27
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- 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
*	fix founded hole in recovery after crash, add vacuum_delay_point()	Teodor Sigaev	2005-06-20

*	1. full functional WAL for GiST	Teodor Sigaev	2005-06-20
\| \| \| \| \| \| \| \| \| \| \|	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 on	Teodor Sigaev	2005-06-14
\| \| \| \| \| \| \|	recovery after crash (power loss etc) it may say that it can't restore index and index should be reindexed. Some refactoring code.
*	Remove the mostly-stubbed-out-anyway support routines for WAL UNDO.	Tom Lane	2005-06-06
\| \| \| \| \| \|	That code is never going to be used in the foreseeable future, and where it's more than a stub it's making the redo routines harder to read.
*	Cleanup GiST header files. Since GiST extensions are often written as	Neil Conway	2005-05-17
	external projects, we should be careful about what parts of the GiST API are considered implementation details, and which are part of the public API. Therefore, I've moved internal-only declarations into gist_private.h -- future backward-incompatible changes to gist.h should be made with care, to avoid needlessly breaking external GiST extensions. Also did some related header cleanup: remove some unnecessary #includes from gist.h, and remove some unused definitions: isAttByVal(), _gistdump(), and GISTNStrategies.
