Okay. When you get back to the original issue, the gold is hidden in
src/backend/optimizer/path/indxpath.c; see the "special indexable
operators" stuff near the bottom of that file. (It's a bit of a crock
that this code is hardwired there, and not somehow accessed through a
system catalog, but it's what we've got at the moment.)
