These entries could never be matched to an index clause because they don't have the index datatype on the left-hand side of the operator. (Their commutators are in the opclass, which is sensible, but that doesn't mean these operators should be.) Spotted by a test that I recently added to opr_sanity to catch exactly this type of thinko. AFAICT there is no code in gistproc.c that is specifically meant to cover these cases, so nothing to remove at that level.
