method. The actual routines are listed elsewhere.
+ By the way, the amorderstrategy entry tells whether
+ the access method supports ordered scan. Zero means it doesn't; if it
+ does, amorderstrategy is the number of the strategy
+ routine that corresponds to the ordering operator. For example, btree
+ has amorderstrategy = 1 which is its
+ "less than" strategy number.
+
+
The next class of interest is pg_opclass. This class exists only to
associate a name and default type with an oid. In pg_amop, every
yet.) If you do not do this, things will still work, but the optimizer's
estimates won't be as good as they could be.
+
+ There are additional selectivity functions designed for geometric
+ operators in src/backend/utils/adt/geo_selfuncs.c: areasel, positionsel,
+ and contsel. At this writing these are just stubs, but you may want
+ to use them (or even better, improve them) anyway.
+
neqjoinsel for <>
scalarltjoinsel for < or <=
scalargtjoinsel for > or >=
+ areajoinsel for 2D area-based comparisons
+ positionjoinsel for 2D position-based comparisons
