Обсуждение: Foreign key in pg_dump / psql
A couple of bits of the depend/constraint patch that were not applied. It displays foreign key structure in /d while skipping the triggers that make up the foreign key. Dumps foreign keys as alter table statements on >=7.3. Older DBs will continue to dump triggers (no pg_constraint table).

The attached better handles constraint triggers which are not foreign keys. It helps 7.2. Is there any reason to create new constraint triggers? Could the CONSTRAINT clause be removed after a couple of releases?

Not without breaking existing pg_dump files. It will be many releases
before you will be able to sell that idea...

Tom has applied this.
