Обсуждение: Restricting user access to databases
Is there anyway to make PostgreSQL automatically only grant access to databases by their owners, and preferably database superusers, rather than making lots of pg_hba.conf entries and password files? It would be nice if there was an option to do this, so then pg_hba.conf would only need editing to allow exceptions to this. It should make administrating a lot a users with many databases much easier. Jared

Just had an idea. Another token could be added to the pg_hba.conf file: 'owner'. Then the line: host all 192.168.3.0 255.255.255.0 password owner Would only allow users that owned the database they were trying to access to login. 'owner' being like a virtual file containing only the owner's name of the database, that the user is trying to access. (Or is there already a way to easily do this?) Jared

Jared,
It doesn't jump out at you but if you read the pg_hba.conf help REALLY
closely you will find that you can do this:
host sameuser 192.168.3.0 255.255.255.0 password
Where "sameuser" under the DBNAME allows connection to a database of the
same name of the user trying to connect. This isn't "quite" what you are
asking for, but if you make sure that users' databases are named the same
as their user account it will work. It really doesn't work for my
situation since our databases aren't specific to "users". You might be
able to work with that though.
