New option: default DSN

[remcohaszing]

Description

By default pgcli connects with /var/run/postgresql/.s.PGSQL.5432, which isn’t running on my device. Most of the time, I need to use pgcli -D local.

I would like pgcli to use the local DSN by default. I imagine this could be done using the following option in the configuration file:

[main]
# The default DSN to connect to when running pgcli.
default_dsn = local
