Tighten ALTER FOREIGN TABLE .. SET DATA TYPE checks.

Browse Source 
If the foreign table's rowtype is being used as the type of a column in
another table, we can't just up and change its data type.  This was
already checked for composite types and ordinary tables, but we
previously failed to enforce it for foreign tables.
