I highly doubt you have any data loss. This line makes me suspect the
firewall:

Also the log suggests the database is running:

ISTM the problem is basically a connection issue. Try changing
listen_addresses = 'localhost'
to
listen_addresses = '*'

(this will allow postgresql to serve connections from any interface on
the box). Also try as Gevik suggested running pg_ctl directly.
