Subject: [PATCH] nixos/paperless: Add pgsql via unix socket example

Finding out how to connect paperless to a PostgreSQL database via unix
sockets and peer authentication took me a few minutes, so leaving a hint
in the extraConfig example seems like a good idea to me.

Also remove unnecessary use of literalExpression for attribute set, it
is only required for complex values like functions or values that depend
on other values or packages.
