Here is a patch for testing query modes on pgbench. It is discussed on
http://archives.postgresql.org/pgsql-hackers/2007-10/msg00755.php
I think this is useful to measure performance of protocols and
prepared statements. I hope the extended protocol will be improved
as fast as the simple protocol. It is 10-20% slower now.
(for 8.4 item)
The querymode option is added:
-M querymode
Choose the query mode from the follows:
simple: using simple query protocol.
extended: using extended protocol.
prepared: using extended protocol with prepared statements.
default is simple.
Usage:
$ pgbench -M [simple|extended|prepared]
