Hi,

It happend several times to me and I think that problem lies in 
environment. When you test this program you are probably logged as user 
xxx which is registered as postgres user.

When httpd runs this program its environment is _strange_. User is 
probably www (is it user a valid postgres user ?). Check also USER env. 
variable which is used by libpq to authenticate connection.

P.S. The nice idea is to set PQTTY variable to log POSTGRES errors on 
server side, or to pipe both stdout and stderr to httpd.
