What would be cool would be some way the developer could alter the plan,

Yeah it would - an implementation I have seen that I like is where the
developer can supply the *entire* execution plan with a query. This is
complex enough to make casual use unlikely :-), but provides the ability
to try out other plans, and also fix that vital query that must run
today.....
cheers

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
