That approach would be doubling down on the assumption that we can always
shoehorn more custom options into SQL-standard constraint clauses, and
we'll never fall foul of shift/reduce problems or future spec additions.
I think for example that USING INDEX TABLESPACE is a blot on humanity,
and I'd be very glad to see pg_dump stop using it in favor of doing
things as Simon suggests.
