Brew upgrade...

Run the usual brew update, and brew upgrade to get the latest 9.4 version of PostgreSQL.

After upgrading PG from 9.3 to 9.4 with brew, the server will not start as is. If you value your database contents, and configuration, pg_upgrade is here to migrate those.

Do not delete the old binaries at once: do not run brew cleanup, because you need 9.3 binaries to migrate.

Migration
