settings.dev: omit most PostgreSQL parameters

If we don't specify all the parameters, one can connect to a local
database server without the need to create a user called "devel", i.e.
you can connect with the same username as your unix username.

This makes it possible to develop lava without the need for a an extra
local_setttings.py file (unless you need to tweak other things beyond
the database connection parameters).
