Remove overly-pessimistic statement about constraint exclusion.
As of 9.2, constraint exclusion should work okay with prepared statements:
the planner will try custom plans with actual values of the parameters,
and observe that they are a lot cheaper than the generic plan, and thus
never fall back to using the generic plan. Noted by Tatsuhito Kasahara.
