That's because the function should actually be,
pg_fetch_array(integer result, integer row)
When in doubt always check the php manual online
at www.php.net. As I said in an earlier e-mail on
this subject, I don't use the standard pgsql functions
within php, I use phpLIB. Sorry for typing the wrong
function, but I was close :)
