Please consider changing the behavior of getpass

First off, this is really a handy tool, I use it a lot, so thank you for making it easy to retrieve the password for Postgres.

... but, I lost a couple of hours last time at work, because of the behavior of getpass, when no match is found. I had misspelled the url in .pgpass, which then returns None as documented:

Return the password for the specified host, port, dbname and user. None will be returned if a
password can not be found for the specified connection parameters.

Although, I didn't know this was expected behavior. I would have assumed some kind of exception, if the password was not found. I think you should consider throwing an exception instead, because I can't see a situation where returning None would be a useful. You would catch a lot of errors like mine this way, and if you really want None, you can just make a try-except.
