On a related matter, which I can make a formal feature request ticket for...
PgAdmin should have a password manager UI that lets you see/retrieve the saved
passwords it uses with remembered servers.
A few months ago I ran into a problem where I had temporarily forgotten what the
password was for a Postgres user, which I needed to use from a separate client,
but PgAdmin seemingly had no built-in way to show the password it remembered.
