That seems to do the trick. This probably solves the problem that I
originally posted.

Though, I am still not sure why we drop the existing connection and
start all over again but now with the newly entered password. This
kind of seems to leave the protocol state machine (as in
PQconnectPoll() ) halfway (after pg_fe_sendauth() failed) in the first
connection attempt for the auth requests requiring the password (or
others, too?). Although, sticking to this design may have to do with
the problems of doing otherwise that I am unaware of.
