PostgreSQL SET ROLE for schema browser and "Jump to Editor"

Is there a way to set the active role for the connection used by the schema explorer and/or the "jump to editor" context menu?

On PostgreSQL many of our tables require the user be a member of a specific group role, especially FWD tables. This is a different group role than the users login role.

In an interactive session I would "SET ROLE powerusers;" but I have not been able to find a way to achieve this for the schema browser' or table editor connections.

Thanks
