And poking at that I have finished with the attached that adds a
CREATE INDEX query before ALTER TABLE ADD CONSTRAINT, to which a USING
INDEX is appended. Storage options as well as building the column list
becomes unnecessary because indexdef already provides everything what
is needed, so this patch makes dump rely more on what is on
backend-side.
