Title: requesting small fix to SQL in Certificate for Postgres

certificate: fixing pgsql error, cannot use GROUP BY so hoping ORDER BY will suffice.

It currently doesn't show the list of Certificates with a Postgres database as Postgres doesn't like that GROUP BY (much fussier than MySQL it seems). I'm assuming it's really just a sort as there are no other aggregate functions. HTH.
