I can't tell if this error is a really an unsupported connection param or pgadmin can't find my pgpass file. I've moved the pspass file to multiple locations but no progress
The server has zero use for a password file, it is a client thing, so a connection option named passfile makes no sense. Where did you get the idea that it would be valid?
Also, pgAdmin the third-party product has its own support list and/or separate site - this list is for basic administration of the server itself.
