How about "prepared" means really "prepared"... in the sense of parsed,
analyzed all sensible plans, and save a meta-plan which based on current
statistics and parameter values chooses one of the considered (and
cached) plans ?
That would be immune both to statistics changes and parameter value
changes in certain limits. It would be also a lot more complex too than
a simple plan...

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
