Sorry, I already see my failure. It is in the fact that Postgres
doesn't support that connection statements yet (but some connection
things are supported - like changing the CURRENT_ROLE).
So, my previous message is interesting only from theoretical point of
view. I always try to thing in the manner of SQL standard or use
knowledge from books/university ...
But the logic is clear, isn't it? Connection is not client operation.
I think that Rafal's proposal is quite interesting (I experience the
same difficulties every time. There was several wrong DROP DATABASE in
my career... :-) )
