One point that comes to mind after more thought is that you'd really
like "create table ... default nextval('foo') ..." to understand that
there is a dependency from the column's default expression to sequence
foo. Currently we hack this to sort-of-work for SERIAL columns, but
I'd like to have a cleaner mechanism.
Is it sane for a literal like 'foo'::regclass to, in itself, create a
dependency? Not sure.
