Hey!  One I can answer!

typos may exist:

pg_Exec($conn, "UPDATE options SET description = '$description', info =
'$info', title = '$title' WHERE product = '$product' AND title =
'$old_title'");

Basically, you can have as many ", field = $value" entries as you like.

I also purposefully stripped off the ';' inside the string because
PostgreSQL doesn't need it, and some other database backend barfs when you
use it, so if you ever want to port, you don't want the ';' as part of the
SQL.  Capiche?
