Hmm - is it the capital "A" here? I notice the second attempt has "a".
Anyway, pgAdmin can display roles/users, and if not "SELECT * FROM
pg_roles" will do so.

No, the database users are completely separate from OS users. By
convention, "postgres" is the OS user of the process and superuser for
the DB, but you could change it if you wanted to.

OK, so you've either got the postgres user password, or none set. That
should let you do everything you want - dump, restore, create users,
reset passwords etc.

Well, with SQL you can do CREATE DATABASE <newdb> TEMPLATE=<olddb>
You should be able to run that from PgAdmin, but there's probably a
dialogue-box that will do it too.

Use postgres as the user for the moment. Once you've figured out which
users you have use ALTER USER or ALTER ROLE to reset their passwords.
See manual for syntax.

Oh, there's a file called ".pgpass" that you can use to hold passwords
on unix-like systems. I think it's called "pgpass.txt" on Windows but
check the manuals for details. It will be readable only by the OS user
that owns it.
