Can't get postgresql to work

I keep getting this when I try to access the PostgreSQL database. The
funny thing is this used to work. I am using a cobalt Linux server.
And Postgresql is used for the GUI on that server . The GUI works I
just can't access this other Database.
How can I start the server with the -i . PostgreSQL is started at boot
up with the script down below how can I change that to use the -i
switch or do I even have to do that. I really don't understand this at
all. How can I get it to work

PHP Warning:  pg_pconnect() unable to connect to PostgreSQL server: PQconnec
tPoll() -- connect() failed: Connection refused
        Is the postmaster running (with -i) at '127.0.0.1'
        and accepting connections on TCP/IP port '5901'?
