I'm trying to remove an old version of Postgres on my local Macbook Pro but cannot figure it out. In PG Admin I see two servers, version 9.2 and 9.4. When I try to run Heroku commands such as pg:pull, its referring to the old server. But my database is located on the new one, version 9.4.

The uninstaller is located in /library/PostgreSQL/9.2/uninstall-postgresql. Running that uninstaller removed my old version and left the newer one in place.

The uninstaller app does not remove everything. The data folder is left. And several config files scattered around the OS folders remain. – Basil Bourque Jun 21 '18 at 03:10
