No, there's no intention of caching plans across sessions.

I'm intending to build some infrastructure in namespace.c to support
a stack of "override" search_path values, and then tweak plancache.c
to override search_path during a replan. (It has to be a stack because
nested replan events are entirely possible.) I think this
infrastructure will also work for attaching search paths to functions;
but we still lack an agreed design spec for how that should look to the
user.
