pg_connect() error

hi guys,
we have a postgres db with a hosting company and have been trying to connect
to. error is below.
*Warning*: pg_connect()
[function.pg-connect<http://hoopsgm.net/test/function.pg-connect>]:
Unable to connect to PostgreSQL server: could not connect to server:
Connection refused Is the server running on host "pgdb1.host-ed.net" and
accepting TCP/IP connections on port 3306?

from my trawling around google i have found that it could be related to the
postgres.conf file and turning on tcpip sockets to true?? (i cannot
view/edit any postgres conf files)

oh and those are the host/port details supplied by hosting provider


any help would be appreciated in pointing on the right path.

Cheers

Arun
