I'm guessing what you mean is that you tried it on the OpenACS web site and it worked? A snippet from your error log would help, but I'm guessing that you don't have the latest and greatest driver compiled for ACS use. Which version of AOLserver are you using? Have you compiled the Postgres driver with the right flags for acs use?
Speaking of which, I should release the newest version of our driver, I think it's behind schedule...
