Of course, when all else fails, you can always fallback to SQLDeveloper http://www.oracle.com/technetwork/developer-tools/sql-develo..., install the postgres jdbc driver https://jdbc.postgresql.org/download.html and ease into Postgres with your usual Oracle client.

It's especially useful if you're already using it on your day/consulting job as it naturally blends into the environment.
