If these are queries that run frequently, then the relevant cache
will probably remain populated[1].  If they _don't_ run frequently, why
do you want to force the memory to be used to optimise something that
is uncommon?  But in any case, there's no mechanism to do this.


[1] there are in fact limits on the caching: if your data set is
larger than memory, for instance, there's no way it will all stay
cached.  Also, VACUUM does nasty things to the cache.  It is hoped
that nastiness is fixed in 8.0.
