Using prepared queries, at least if you use PQexecPrepared or
PQexecParams, also reduces the work required on the client to build the
whole string, and the parsing overhead on the database side to pull it
apart again.  That's where the performance is going to be improved by
going that route, not so much in eliminating the planning.
