Since the only user who can connect to a fresh install is the postgres user, here is how to create yourself a database account (which is in this case also a database superuser) with the same name as your login name and then create a password for the user: sudo -u postgres createuser -superuser $USERĬlient programs, by default, connect to the local host using your Ubuntu login name and expect to find a database with that name too. Check out the excellent Postgresql documentation for more information, but essentially this means that if your Ubuntu username is 'foo' and you add 'foo' as a Postgresql user then you can connect to the database without requiring a password. If you don't intend to connect to the database from other machines, this alternative setup may be simpler.īy default in Ubuntu, Postgresql is configured to use 'ident sameuser' authentication for any connections from the same machine. Then to activate the extension, for ""Postgresql 8.4"", run the adminpack.sql script, simply type: sudo -u postgres psql < /usr/share/postgresql/8.4/contrib/adminpack.sqlįor "Postgresql 9.3"+ install the adminpack "extension" in the "postgres" database: The "adminpack" addon, which it calls Server Instrumentation, is part of postgresql-contrib, so you must install that package if you haven't already:

"postgres", to the database called "postgres" (1st argument to psql). This connects as a role with same name as the local user, i.e. As the local “postgres” Linux user, we are allowed to connect and manipulate the server using the psql command. To start off, we need to set the password of the PostgreSQL user (role) called "postgres" we will not be able to access the server externally otherwise. You may also use the Synaptic package manager from the System>Administration menu to install these packages. PgAdmin III is a handy GUI for PostgreSQL, it is essential to beginners. Installing PostGIS, procedural languages, client interfaces, etcĪdditional packages contain procedural language runtimes, add-ons like PostGIS, language client interfaces like psycopg2 for Python, etc. See "External Links" below for options for getting newer releases.
