I don't find that to be a good idea at all. pg_dump is probably not the
only code that believes it can select a creation target with search_path,
no matter what that target is.
As for back-patchability, I was initially thinking of only fixing this in
HEAD. If the behavior change is small enough, maybe we could get away
with back-patching 9.2 and 9.3; but I don't think we should start with
the assumption that we must do that.
