postgres_fdw: Fix incorrect NULL handling in join pushdown.
something.* IS NOT NULL means that every attribute of the row is not
NULL, not that the row itself is non-NULL (e.g. because it's coming
from below an outer join. Use (somevar.*)::pg_catalog.text IS NOT
NULL instead.

Amit Langote and Etsuro Fujita. Schema-qualification added by me.
