Alvaro Herrera	b0b7be6133	Add BRIN infrastructure for "inclusion" opclasses ... This lets BRIN be used with R-Tree-like indexing strategies. Also provided are operator classes for range types, box and inet/cidr. The infrastructure provided here should be sufficient to create operator classes for similar datatypes; for instance, opclasses for PostGIS geometries should be doable, though we didn't try to implement one. (A box/point opclass was also submitted, but we ripped it out before commit because the handling of floating point comparisons in existing code is inconsistent and would generate corrupt indexes.)

Alvaro Herrera	26df7066cc	Move strategy numbers to include/access/stratnum.h ... For upcoming BRIN opclasses, it's convenient to have strategy numbers defined in a single place. Since there's nothing appropriate, create it. The StrategyNumber typedef now lives there, as well as existing strategy numbers for B-trees (from skey.h) and R-tree-and-friends (from gist.h). skey.h is forced to include stratnum.h because of the StrategyNumber typedef, but gist.h is not; extensions that currently rely on gist.h for rtree strategy numbers might need to add a new A few .c files can stop including skey.h and/or gist.h, which is a nice side benefit.

Bruce Momjian	0a78320057	pgindent run for 9.4 ... This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.	12 years ago
Tom Lane	f23a5630eb	Add an in-core GiST index opclass for inet/cidr types. ... This operator class can accelerate subnet/supernet tests as well as btree-equivalent ordered comparisons. It also handles a new network operator inet && inet (overlaps, a/k/a "is supernet or subnet of"), which is expected to be useful in exclusion constraints. Ideally this opclass would be the default for GiST with inet/cidr data, but we can't mark it that way until we figure out how to do a more or less graceful transition from the current situation, in which the really-completely-bogus inet/cidr opclasses in contrib/btree_gist are marked as default. Having the opclass in core and not default is better than not having it at all, though. While at it, add new documentation sections to allow us to officially document GiST/GIN/SP-GiST opclasses, something there was never a clear place to do before. I filled these in with some simple tables listing the existing opclasses and the operators they support, but there's certainly scope to put more information there.
