* Assign a "unique" number for a prepared statement. * * This works much like GetCursorNumber, except that we never reset the counter * within a session. That's because we can't be 100% sure we've gotten rid * of all prepared statements on all connections, and it's not really worth * increasing the risk of prepared-statement name collisions by resetting. */
