Quoth the manual (7.4):Presently, prepared statements for use with PQexecPrepared must be set up 
by executing an SQL PREPARE command, which is typically sent with PQexec 
(though any of libpq's query-submission functions may be used). A 
lower-level interface for preparing statements may be offered in a future 
release.

Does the new, 8.0 libpq have an interface to the prepare protocol message?
