      To supplement what Johann said below.....

      - you should determine what UID your CGI process is running as (typically "nobody") ... and whether this UID has necessary psql permissions
      - you should determine the PATH available to your CGI process (typically quite limited) ... perhaps your process isn't able to find the psql command

      Does psql have permission to run and connect to the db as the user under
      which the cgi is run as?
