Following are what i do to enable remote connection: 1. edit/usr/local/pgsql/data/postgresql.confenable remote tcp/ip connection:listen_addresses = '*'port = 5432max_connection = 100 2. edit/usr/local/pgsql/data/pg_hba.confadd remote client that will connect to the server to pg_hba.conf for example:PC_Server IP: 192.168.1.98 Running PostgreSQL Server.
