Re: problem with foreign keys + data-only backup

Hi,

I do not think this will work. As far as I know foreign key checks are
not triggers. Postgres is very strict with things concerning referential
integrity so you cannot turn them off.

Maybe it will help to use "--orig-order" for creating the dump.
