Just to clarify a small point here - there's no such thing as connecting
to a PostgreSQL database without first connecting to a server. Clients
don't have any access to the data on disk; the server always does the
serving. :-)

Yes, you do. The "name" field is up to you - it's just a label in
PgAdmin used to identify the server in the list.

This depends on (i) how authentication is set up in Postgres, and (ii)
how you are connecting. According to the above pg_hba.conf, if you
connect via a Unix socket ("local" rules), Postgres will use ident for
authentication; whereas if you connect over TCP/IP ("host" rules) it
will just let you straight in without any authentication ("trust").
Remember too that the order of rules in pg_hba.conf is important - the
first matching rule will take effect.
