pgsql: Fix binary upgrade of altered typed tables

Fix binary upgrade of altered typed tables

Instead of dumping them as CREATE TABLE ... OF, dump them as normal
tables with the usual special processing for dropped columns, and then
attach them to the type afterward, using ALTER TABLE ... OF. This is
analogous to the existing handling of inherited tables.
