Sounds pretty reasonable to me, but I would just caution that we should
check if that's considered 'leakproof' or not (or, if it is, if it'd
ever possibly leak data it shouldn't or if it would only ever return
information provided by the user).

Otherwise, someone might be able to convince the planner to push it down
below a security qual and expose data from rows which shouldn't be
visible.
Thanks!
