* WAL for GiST. It work for online backup and so on, but onTeodor Sigaev2005-06-141-2/+2
| | | | | | | recovery after crash (power loss etc) it may say that it can't restore index and index should be reindexed. Some refactoring code.
* Cleanup GiST header files. Since GiST extensions are often written asNeil Conway2005-05-171-2/+3
| | | | | | | | | | | | 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.
* GiST improvements:Neil Conway2005-05-171-193/+184
| | | | | | | | | | | | | | | | | | | - make sure we always invoke user-supplied GiST methods in a short-lived memory context. This means the backend isn't exposed to any memory leaks that be in those methods (in fact, it is probably a net loss for most GiST methods to bother manually freeing memory now). This also means we can do away with a lot of ugly manual memory management in the GiST code itself. - keep the current page of a GiST index scan pinned, rather than doing a ReadBuffer() for each tuple produced by the scan. Since ReadBuffer() is expensive, this is a perf. win - implement dead tuple killing for GiST indexes (which is easy to do, now that we keep a pin on the current scan page). Now all the builtin indexes implement dead tuple killing. - cleanup a lot of ugly code in GiST
* First steps towards index scans with heap access decoupled from indexTom Lane2005-03-271-1/+28
| | | | | | | | | | access: define new index access method functions 'amgetmulti' that can fetch multiple TIDs per call. (The functions exist but are totally untested as yet.) Since I was modifying pg_am anyway, remove the no-longer-needed 'rel' parameter from amcostestimate functions, and also remove the vestigial amowner column that was creating useless work for Alvaro's shared-object-dependencies project. Initdb forced due to changes in pg_am.
* Marginal hack to merge adjacent ReleaseBuffer/ReadBuffer calls intoTom Lane2005-02-051-16/+22

* Cross-data-type comparisons are now indexable by btrees, pursuant to myTom Lane2003-11-121-16/+27
| | | | | | | | | | pghackers proposal of 8-Nov. All the existing cross-type comparison operators (int2/int4/int8 and float4/float8) have appropriate support. The original proposal of storing the right-hand-side datatype as part of the primary key for pg_amop and pg_amproc got modified a bit in the event; it is easier to store zero as the 'default' case and only store a nonzero when the operator is actually cross-type. Along the way, remove the long-since-defunct bigbox_ops operator class.
* Add operator strategy and comparison-value datatype fields to ScanKey.Tom Lane2003-11-091-16/+6
| | | | | | | | | | | Remove the 'strategy map' code, which was a large amount of mechanism that no longer had any use except reverse-mapping from procedure OID to strategy number. Passing the strategy number to the index AM in the first place is simpler and faster. This is a preliminary step in planned support for cross-datatype index operations. I'm committing it now since the ScanKeyEntryInitialize() API change touches quite a lot of files, and I want to commit those changes before the tree drifts under me.

* Restructure indexscan API (index_beginscan, index_getnext) perTom Lane2002-05-201-75/+37
| | | | | | | yesterday's proposal to pghackers. Also remove unnecessary parameters to heap_beginscan, heap_rescan. I modified pg_proc.h to reflect the new numbers of parameters for the AM interface routines, but did not force an initdb because nothing actually looks at those fields.
* I was digging through the GiST code, and figured I'd fix up some of theBruce Momjian2002-03-051-4/+2
| | | | | | | | | | | | "bad smell" in that code. Stuff like function parameters that aren't used, typos in the comments, comparison between signed and unsigned ints, etc. Attached is a pretty trivial patch; it compiles, but beyond that completely untested. Unless anyone sees any problems, please apply for 7.3. Neil Conway

* Update GiST for new pg_opclass arrangement (finally a clean solutionTom Lane2001-08-221-3/+3

| | | | | | | | | | | | | | (as proposed in http://fts.postgresql.org/db/mw/msg.html?mid=1028327) 2. support for 'pass-by-value' arguments - to test this we used special opclass for int4 with values in range [0-2^15] More testing will be done after resolving problem with index_formtuple and implementation of B-tree using GiST 3. small patch to contrib modules (seg,cube,rtree_gist,intarray) - mark functions as 'isstrict' where needed. Oleg Bartunov
* Updates to make GIST work with multi-key indexes (from Oleg BartunovTom Lane2001-05-311-11/+16

* Thank god for searchable mail archives.PostgreSQL Daemon1998-01-151-2/+2
| | | | | | | | | Patch by: wieck@sapserv.debis.de (Jan Wieck) One of the design rules of PostgreSQL is extensibility. And to follow this rule means (at least for me) that there should not only be a builtin PL. Instead I would prefer a defined interface for PL implemetations.

* From: Dan McGuirk <mcguirk@indirect.com>Marc G. Fournier1997-03-121-4/+4
| | | | | | | | | | Subject: [HACKERS] linux/alpha patches These patches lay the groundwork for a Linux/Alpha port. The port doesn't actually work unless you tweak the linker to put all the pointers in the first 32 bits of the address space, but it's at least a start. It implements the test-and-set instruction in Alpha assembly, and also fixes a lot of pointer-to-integer conversions, which is probably good anyway.
