Given the NOTES in the man page, how do we determine if a user and

Literally every other shell program that requires logging into the database will fail if invalid credentials are provided.
Or, you can use good credentials and psql to connect to a known database and then query the system to learn, without an error, if other roles or databases exist in the same cluster.
