Tom Lane 9220362493 Teach SP-GiST to do index-only scans. ... Operator classes can specify whether or not they support this; this preserves the flexibility to use lossy representations within an index. In passing, move constant data about a given index into the rd_amcache cache area, instead of doing fresh lookups each time we start an index operation. This is mainly to try to make sure that spgcanreturn() has insignificant cost; I still don't have any proof that it matters for actual index accesses. Also, get rid of useless copying of FmgrInfo pointers; we can perfectly well use the relcache's versions in-place.		2011-12-19 14:58:41 -05:00
