Unless there's something underlying that proposal that I'm not seeing,
it only deals with one of the problems in this area. The security-
related issues remain unsolved.
AFAICS there's a pretty fundamental tension here around the question
of how hard it is to revert to the original role. If it's not possible
to do that then a connection pooler can't serially reuse a connection for
different users, which largely defeats the point. If it is possible, how
do you keep that from being a security hole, ie one of the pool users can
gain privileges of another one?
(And, btw, I repeat that all of this has been discussed before on our
lists.)
