Bruce Momjian f1312b5ed3 Add postgres.h to *.c files for pg_upgrade, ltree, and btree_gist, and 
remove from local *.h files.

Per suggestion from Alvaro.

Tom Lane bb85030630 Fix contrib/btree_gist to handle collations properly. 
Make use of the collation attached to the index column, instead of
hard-wiring DEFAULT_COLLATION_OID.  (Note: in theory this could require
reindexing btree_gist indexes on textual columns, but I rather doubt anyone
has one with a non-default declared collation as yet.)

Bruce Momjian bf50caf105 pgindent run before PG 9.1 beta 1. 2011-04-10 11:42:00 -04:00
Tom Lane 8436489c81 Add KNNGIST support to contrib/btree_gist. 
This extends GiST's support for nearest-neighbor searches to many of the
standard data types.

Magnus Hagander 9f2e211386 Remove cvs keywords from all files. 2010-09-20 22:08:53 +02:00
Robert Haas ad17ff95cf Add btree_gist support for searching on "not equals". 
Jeff Davis, with slight editorialization by me.

Bruce Momjian d747140279 8.4 pgindent run, with new combined Linux/FreeBSD/MinGW typedef list 
provided by Andrew.

Andrew Dunstan 53972b460c Add $PostgreSQL$ markers to a lot of files that were missing them. 
This particular batch was just for *.c and *.h file.

The changes were made with the following 2 commands:

find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o  \( -name '*.[ch]'  \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | while read file ; do head -n 1 < $file | grep -q '^/\*' && echo $file; done | xargs -l sed -i -e '1s/^\// /' -e '1i/*\n * $PostgreSQL:$ \n *'

find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o  \( -name '*.[ch]'  \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | xargs -l sed -i -e '1i/*\n * $PostgreSQL:$ \n */'

Tom Lane 8472bf7a73 Allow float8, int8, and related datatypes to be passed by value on machines 
where Datum is 8 bytes wide.  Since this will break old-style C functions
(those still using version 0 calling convention) that have arguments or
results of these types, provide a configure option to disable it and retain
the old pass-by-reference behavior.  Likewise, provide a configure option
to disable the recently-committed float4 pass-by-value change.

Zoltan Boszormenyi, plus configurability stuff by me.
 2008-04-21 00:26:47 +00:00
Alvaro Herrera 7861d72ea2 Modify the float4 datatype to be pass-by-val. Along the way, remove the last 
uses of the long-deprecated float32 in contrib/seg; the definitions themselves
are still there, but no longer used.  fmgr/README updated to match.

I added a CREATE FUNCTION to account for existing seg_center() code in seg.c
too, and some tests for it and the neighbor functions.  At the same time,
remove checks for NULL which are not needed (because the functions are declared
STRICT).

I had to do some adjustments to contrib's btree_gist too.  The choices for
representation there are not ideal for changing the underlying types :-(

Original patch by Zoltan Boszormenyi, with some adjustments by me.

Teodor Sigaev 1f7ef548ec Changes 
* new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php)
  * possible call pickSplit() for second and below columns
  * add spl_(l|r)datum_exists to GIST_SPLITVEC -
    pickSplit should check its values to use already defined
    spl_(l|r)datum for splitting. pickSplit should set
    spl_(l|r)datum_exists to 'false' (if they was 'true') to
    signal to caller about using spl_(l|r)datum.
  * support for old pickSplit(): not very optimal
    but correct split
* remove 'bytes' field from GISTENTRY: in any case size of
  value is defined by it's type.
* split GIST_SPLITVEC to two structures: one for using in picksplit
  and second - for internal use.
* some code refactoring
* support of subsplit to rtree opclasses

TODO: add support of subsplit to contrib modules

Neil Conway 36ab600511 Cleanup of GiST extensions in contrib/: now that we always invoke GiST 
methods in a short-lived memory context, there is no need for GiST methods
to do their own manual (and error-prone) memory management.
 2005-05-21 12:08:06 +00:00
Neil Conway 8d6e9bca37 This patch makes some minor style cleanups to contrib/btree_gist: remove 
the "extern" keyword from function definitions, reorganize some
PG_GETARG_XXX() usage, and similar.

Tom Lane 86d78021a4 Whack btree_gist code around until it has some small hope of building 
on non-gcc compilers.
