when using pgpassfile only dbname=postgres works

[openbrian]

Just letting you know about this issue.

Since there's no way to specify the name of the database to connect to in servers.json, the default "postgres" is used. If your pgassfile has something different, like the real name of the database, the entry in the pgpassfile will not be used.

I created this issue with the pgadmin team. redmine.postgresql.org/issues/7577
