Changes by: tgl(at)postgresql(dot)org 03/05/13 00:38:58
Modified files:
src/backend/optimizer/path: indxpath.c
src/backend/utils/cache: lsyscache.c syscache.c
src/backend/utils/sort: tuplesort.c
src/include/catalog: catversion.h indexing.h
Log message:
Change pg_amop's index on (amopclaid,amopopr) to index (amopopr,amopclaid).
This makes no difference for existing uses, but allows SelectSortFunction()
and pred_test_simple_clause() to use indexscans instead of seqscans to
locate entries for a particular operator in pg_amop. Better yet, they can
use the SearchSysCacheList() API to cache the search results.
