Someone asked me in email
"What's the no-parse option?"
The Oracle driver implements bind variables, it does not however parse queries the first time it comes accross them, retrieve a statement handle, and use that handle with bind variables for subsequent invocations. Oracle's data above suggests this will be almost twice as fast as bind variables alone, depending on the query of course.
Looking through the Postgres docs I thought it might be possible to cheat bind variable, pre-parsed statement support... Queries in PL/PGSQL *are* cached (mentioned above), and the client side C API supports executing a procedure with arguments (as apposed to dumping the text to execute a procedure into a select statement). Unfortunately procedures in Postgres cannot return relations (yet).
