Re: pgsql: Add infrastructure to support EphemeralNamedRelation references.

rhinoceros says you missed contrib/sepgsql.

More generally, if you hack the API of some globally-referenced function,
you ought to grep for references to it rather than just assume your
compiler will find them all for you.  For one thing, that approach is a
great way to fail to update relevant comments.

(And while I'm bitching, you definitely failed to update ProcessUtility's
header comment, which like most significant functions takes some pains
to describe all the arguments.)
