Well. RESET ALL in a pooler sets values to the initial connection values the
pooler had, not the ones of pooled connection.
On the same time there are multiple people complaining about such default
values being contraproductive to pooling environments because they reset to
the wrong values.
I dont really get that argument - the pooler should just issue a SET
CONNECTION DEFAULT for all connection values. That would make it far more
transparent than before...

As I had initially suggested something like that I agree here.
