But it is not pg_dump's charter to enforce that deprecation. Maybe what you are asking is why it uses SET default_with_oids rather than attaching WITH OIDS to the CREATE TABLE commands. That was done as a compatibility measure so that the dump files would still be readable by PG versions that didn't understand WITH OIDS --- they'd reject the SET commands but still accept the CREATE TABLE commands. By the same token the files are a shade more portable to other DBMSes than they would be with WITH OIDS clauses. Neither of these arguments is hugely compelling, perhaps, but avoiding the use of a variable isn't very compelling either ... regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
