Обсуждение: Bytea and pg_dump/dumpall

Just a quick question:

Bytea columns are backed up appropriately using pg_dump/dumpall?  The docs
mention specifics about large objects, and I just wanted to check whether
bytea is considered a large object in regard to backup.

Thanks,
Sean

Yes, bytea columns are dumped/restored as any other column type.
Large objects are a different type created using a separate API:

bytea is just data.
