Hi there,
Are you running the Postgres postmaster with -i, to allow remote
connections? -- and is your pg_hba.conf
file edited so as to allow connections from the IP address you're using?
Even if it's your local machine you're testing on, you have to have
Postgres set up to allow TCP/IP connections if you want to test CGI
scripts. (At least, I think that's right: please do correct me, anyone who
knows different.)
best,
Mo
