Quite a lot of the code considers "relation" to mean "anything that has
a pg_class entry", which is a definition that's gotten fuzzier and
fuzzier as we've thrown more stuff into pg_class. (Standalone composite
types, for example, hardly qualify as a relation by anyone's
understanding of the term. But they have pg_class entries now.)
I don't mind rewording error messages to say "table" when in fact they
could only be referring to plain tables. But let's not just move the
fuzziness over from "relation" to "table".
