No. The design of session_replication_role was to enable quick disabling of *all* triggers and rules, including system ones. When you enter that mode, it is assumed that you know what you are doing enough to not create an inconsistency. With Slony and Bucardo, for example, all tables affected by the triggers (e.g. a cascaded delete from a FK) are changed together. > 2.

If you want the constraint triggers to fire, but not other user triggers, your best bet is to do: ALTER TABLE foo DISABLE TRIGGER USER; This has a heavy table locking cost, but does exactly what you want: disables all non-system/FK triggers. Your next best bet is probably to emulate the effects of the FK trigger yourself, e.g. deleting from the child table while in 'replica' mode. A further option may be to give your user functions some brains, such that they will not execute when session_replication_role is set to 'local', for example. While I do think session_replication_role needs some more granularity, it's also a little hard to say more without knowing your exact requirements. - -- Greg Sabino Mullane greg@xxxxxxxxxxxx End Point Corporation http://www.endpoint.com/ PGP Key: 0x14964AC8 201304251145 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iEYEAREDAAYFAlF5UHAACgkQvJuQZxSWSsjm+ACeOT2v7EF90tFr7K892UxIAqnl WpwAoKPkIMC7HTTtvOMj/XbtOVGXe0Fl =2bjH -----END PGP SIGNATURE----- -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
