Обсуждение: Referencing to system catalog problem
I am logged in as superuser. I am trying to create something similar to this: Code: CREATE TABLE tbl_unit_convfunctions( unit_from integer REFERENCES tbl_units (unit_id), unit_to integer REFERENCES tbl_units (unit_id), proc_id oid REFERENCES pg_proc (oid) )but no matter what I refer to from pg_proc, i get the error message: ERROR: permission denied: "pg_proc" is a system catalog SQL state: 42501 Has anyone any suggestions how to do something similar, or even better: how to solve this error. I couldn't find any useful information on the net about this issue. Thanks, Davor Original post: http://forums.devshed.com/postgresql-help-21/referencing-to-system-catalog-problem-670063.html Note: OID's are unique in that table, and should be referable, and I explicitely granted the REFERENCE priviledge to the superuser.

You can't have FKs to system tables. See this post for explanation: http://archives.postgresql.org/pgsql-general/2004-12/msg00840.php -- Adrian Klaver adrian.klaver@gmail.com
Thank you Adrian. I apparently missed that post. Guess I will have to come up with an different approach.
