OK, I added this TODO:
* Allow finer control over the caching of prepared query plans
Currently, queries prepared via the libpq API are planned on first
execute using the supplied parameters --- allow SQL PREPARE to do the
same. Also, allow control over replanning prepared queries

There is one problem with the optimizer that is a constant source of
frustration. When using prepared statements and functions (particularly
where function parameters are passed to a query), the optimizer often
fails to utilize an index inside a plan.
This is a well known problem because the

Merlin,
This will most likely never be accepted by the core team because it is
better to spend more time on fixing the planner than to invent some
non-standard.
As far as I know some databases support a syntax where hints can be
hidden in comments or something like that.
