Andres Freund	01368e5d9d	Split all OBJS style lines in makefiles into one-line-per-entry style. When maintaining or merging patches, one of the most common sources for conflicts are the list of objects in makefiles. Especially when the split across lines has been changed on both sides, which is somewhat common due to attempting to stay below 80 columns, those conflicts are unnecessarily laborious to resolve. By splitting, and alphabetically sorting, OBJS style lines into one object per line, conflicts should be less frequent, and easier to resolve when they still occur.

Alexander Korotkov	2a6368343f	Add support for nearest-neighbor (KNN) searches to SP-GiST Currently, KNN searches were supported only by GiST. SP-GiST also capable to support them. This commit implements that support. SP-GiST scan stack is replaced with queue, which serves as stack if no ordering is specified. KNN support is provided for three SP-GIST opclasses: quad_point_ops, kd_point_ops and poly_ops (catversion is bumped). Some common parts between GiST and SP-GiST KNNs are extracted into separate functions.

Tom Lane	65c5fcd353	Restructure index access method API to hide most of it at the C level. This patch reduces pg_am to just two columns, a name and a handler function. All the data formerly obtained from pg_am is now provided in a C struct returned by the handler function. This is similar to the designs we've adopted for FDWs and tablesample methods. There are multiple advantages. For one, the index AM's support functions are now simple C functions, making them faster to call and much less error-prone, since the C compiler can now check function signatures. For another, this will make it far more practical to define index access methods in installable extensions. A disadvantage is that SQL-level code can no longer see attributes of index AMs; in particular, some of the crosschecks in the opr_sanity regression test are no longer possible from SQL. We've addressed that by adding a facility for the index AM to perform such checks instead. (Much more could be done in that line, but for now we're content if the amvalidate functions more or less replace what opr_sanity used to do.) We might also want to expose some sort of reporting functionality, but this patch doesn't do that. Alexander Korotkov, reviewed by Petr Jelínek, and rather heavily editorialized on by me.	10 years ago
Tom Lane	8daeb5ddd6	Add SP-GiST (space-partitioned GiST) index access method. SP-GiST is comparable to GiST in flexibility, but supports non-balanced partitioned search structures rather than balanced trees. As described at PGCon 2011, this new indexing structure can beat GiST in both index build time and query speed for search problems that it is well matched to. There are a number of areas that could still use improvement, but at this point the code seems committable. Teodor Sigaev and Oleg Bartunov, with considerable revisions by Tom Lane	14 years ago

Tom Lane	787eba734b	When creating a large hash index, pre-sort the index entries by estimated bucket number, so as to ensure locality of access to the index during the insertion step. Without this, building an index significantly larger than available RAM takes a very long time because of thrashing. On the other hand, sorting is just useless overhead when the index does fit in RAM. We choose to sort when the initial index size exceeds effective_cache_size. This is a revised version of work by Tom Raney and Shreya Bhargava.	18 years ago

PostgreSQL Daemon	969685ad44	$Header: -> $PostgreSQL Changes ...	22 years ago
Tom Lane	c1d62bfd00	Add operator strategy and comparison-value datatype fields to ScanKey. 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.	22 years ago
Peter Eisentraut	424f0edcb8	Fix relative path references so that make knowns which dependencies refer to one another. Sort out builddir vs srcdir variable namings. Remove some now obsoleted make variables.	25 years ago
Tom Lane	091126fa28	Generated header files parse.h and fmgroids.h are now copied into the src/include tree, so that -I backend is no longer necessary anywhere. Also, clean up some bit rot in contrib tree.	26 years ago

Bruce Momjian	1e801a8f16	Hi, Attached you'll find a (big) patch that fixes make dep and make depend in all Makefiles where I found it to be appropriate. It also removes the dependency in Makefile.global for NAMEDATALEN and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh a little smarter. This no longer requires initdb.sh that is turned into initdb with a sed script when installing Postgres, hence initdb.sh should be renamed to initdb (after the patch has been applied :-) ) This patch is against the 6.3 sources, as it took a while to complete. Please review and apply, Cheers, Jeroen van Vianen	28 years ago

Marc G. Fournier	e2d9501094	Clean up the Makefiles Essentially, this cleans things up so that if PORTNAME isn't defined (I'm working on getting rid of it for FreeBSD, at least, to see if its possible) none of the PORTNAME related stuff gets passed around. Had a little bit of -I related redundancy as well	28 years ago
