Hi, Although I'm quite happy with the way my system (Debian sid) has set up the server (PosgreSQL 9.1), I'm not sure I'm using the authentication/privilege mechanism properly. In particular, I'd like to understand how the administrative user (postgres) is set up. Here is what pg_hba contains: # Database administrative login by Unix domain socket local all postgres peer With peer authentication, one can only login as postgres from a local connection. I'm not sure what password the postgres user was set up in the OS, however, I assigned one to it (the same as for the PostgreSQL user). I've read somewhere that the postgres OS user should be left locked without password, although it's not clear what was meant by "locked". In any case, what is recommended practice WRT passwords for setting Unix vs PostgreSQL passwords for postgres and other DB users?
