Multiple statements in one prepare

How can multiple SQL statements be included in one prepare command? The goal is to reduce chatter between the client and server by submitting an atomic tranasaction set. My interface is libpq.

They can't.  Consider using a plpgsql function, instead.

You can submit multiple PREPARE commands in one query string (separated
by semi-colons), so the difference in FE/BE traffic should be
negligible.
