Yeah, I think this is an ancient value judgement. Sure, it's pretty
questionable whether spawning a backend a second time is better than
tying one up waiting for a human to type a password. (It's going to
be spending a lot of time waiting for that human later on, anyway.)
The real point IMO is that libpq's connection API is already
unreasonably complicated, and providing a callback of this sort
would make it even messier. A different client library might make
a different choice, perhaps.
