If one role owns all the tables in that database, you can make your role a member of that role: GRANT owner_role TO your_role; But are you really sure that your user needs permissions on everything? Yes, well not for everything but for 90% of the tables. The person before me use postgres user in front end apache to storing and fetching data from tables. Front end work with whole database, insert new data on tables, fetching. I want to replace usage of postgres super user. Last night when read documentation I understand it exact as what David J explain in second mail on the list. Why I say "little scared" because tables in database is over 150 plus sequences .. almost 200 objects. Giving separate permission on every single table to user, this it's seems bad idea for me, because in future if I need to change something or add/remove new tables I always should give permissions and if I forgot front end will display errors. From other side is a very good that I can say what user in which tables and fields have permissions, but it's seems in this case I can't use it. Last think that coming in my mind is to change owner to all tables in database my_db from current user (postgres) to my new user (my_user). Any advice what I can do ?

You probably need to read this: http://stackoverflow.com/questions/11599533/postgresql-8-4-grant-dml-privileges-on-all-tables-to-a-role That while that question is about 8.4 so it doesn't cover ALTER DEFAULT PRIVILEGES (http://www.postgresql.org/docs/current/static/sql-alterdefaultprivileges.html), which is the right way to to solve this going forward. It should be useful, though. -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I have a similar situation; I want to have a userid for doing the regular backups, which therefore (for pg_dump) needs SELECT privilege on all tables. Is: GRANT SELECT ON ALL TABLES IN SCHEMA public TO backup_userid; GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO backup_userid; the right way to do this? (Obviously I need to also do this for every other schema I use.) Alternatively, is there some better way to do backups? I'd rather not snapshot the entire data directory; we burn to disc, so a larger backup requires more media and slower backup/restore process.

A database is a distinct object type with its own actions to allow/disallow (mainly connect, usage?). You need to issue similar commands for schemas, tables, functions, etc... Would suggest creating group (i.e., non-login) roles and grant to those then make the user (i.e., login) roles a member of the appropriate group role(s).
