I was going to post this yesterday, but some might have thought that it was a joke. April 1st is always an annoying day to communicate real information.
If you have been fond of the way Debian and Ubuntu manage multiple PostgreSQL versions in parallel, you can now have the same on OS X with Homebrew:
brew tap petere/postgresql brew install postgresql-9.2 # etc. brew install --HEAD postgresql-common
postgresql-common is the same code as in Debian, only mangled a little.
Now you have all the client programs symlinked through
you can use the server management tools such as:
pg_createcluster 9.2 main pg_ctlcluster 9.2 main start pg_lsclusters
Let me know if you find this useful.Links:
