Here is what I have so far (not sure of my conditionals yet or if I need
any joins for them):
select attname from pg_attribute
where attrelid = 'postgres.public.test'::regclass
and attstattarget=-1
and attisdropped='f'
order by attnum asc
Very simple and elegant, you guys rule.
Couple things I want to verify - will this regclass method have any
cases where security would make it less reliable than say, using pg_*?
Also compatibility issues?: are there any server or session/driver modes
that would somehow prevent this from working?
