I can't log from the phppgadmin. I have login failed.
First, I am not sure if I shall log with my unix account or postgres
role (I guess the latter one).

Log:
LOG: database system is ready to accept connections
LOG: connection received: host=[local]
LOG: connection received: host=::1 port=39999
FATAL: no pg_hba.conf entry for host "::1", user "mediawiki",
database "postgres", SSL off

I see there is a problem in my pg_hba.conf, but can't see how to set
up it correctly.

Thank you for hints.
