It looks like that is the result id (like it says :) for that particular
query. You now need to do something like:
$max_value = get_value($maxid);
query isn't the standard postgres function... it's pg_query, so I'm not
sure what else is going on... check the postgresql section of the PHP
manpage for more info.
