Homebrew postgres broken

Question

I installed Postgresql 9.4.0 installed on my Mac (10.10.1/Yosemite) using homebrew. It does not work.

I have created the softlink to /usr/local/opt/postgresql/homebr

Answer 1

In case anyone upgraded from a previous version, dont forget to:

brew postgresql-upgrade-database

That will solve the problem by upgrading your existing databases to the version you upgraded postgres to.
