I think we need SQL standard IDENTITY columns before we can consider adding SQL standard CONTINUE IDENTITY or RESTART IDENTITY clauses. The reason the last attempt to add them petered out was precisely because they *don't* exactly line up with the semantics of sequences so I don't imagine attempting to shoehorn sequences into these clauses is likely to pan out. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's RemoteDBA services! -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
