If you have multiple databases then main_admin would have to connect and disconnect over and over in order to look at each database. If you are setting this up for students to learn RDBMS skills, then wouldn't you be better off with a single database instance containing multiple schemas? Create all the roles with the necessary privileges, then:- CREATE SCHEMA db_a AUTHORIZATION us_a; GRANT ALL ON ALL TABLES IN SCHEMA db_a TO main_admin; Repeat as necessary for each schema/role combination. Then main_admin would have to prefix all tables, sequences, etc. with the schema name in order to run queries, etc. HTH, Rob -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
