Uninstall postgresql mac install#
This is how I usually install postgres on Mac OSX, and it outlined in the post Install postgreSQL and postGIS. This post is only relevant if you installed postgres using Homebrew on Mac OSX. Getting Back to an Old PostgreSQL Specific Version Introduction Trying some of them, I got no one to work properly. I found a number of suggested solutions on stackoverflow. I tried restoring the postgreSQL setup uing a backup (Mac OSX TimeMachone) but secondary connection problems and incomplete installation were reported errors. Without it, it is not possible to restore or migrate your database. The Homebrew update had deleted my active postgreSQL installation (under Cellar etc). In the end I could not solve the problem. It, however, assumes that your original installation Homebrew installation of postgres is intact. It seems to me to be the best source for solving connection problems related to Homebrew updated. Trying to solve the problem I discovered the page Migrating Homebrew Postgres to a New Version by Olivier Lacan. I could restore the postgres installation from my backups (Mac OSX TimeMachine), but I could not manage to restore the connection to the actual database. But I also needed the postgres version associated with the database, and that was gone. Until I discovered that the postgres version I had been using was missing and had been replaced by the latest version. I tried several suggestions that I found in various fora online. One of the consequences was that my postgres server could not start, and I could not access the GeoImagine Framework database. For some reason my postgres setup had a havoc following an upgrade of my Homebrew installation that I, involuntarily, happened to start.
