Upgrade PostgreSQL 9.5.5 to 9.6.1 using Homebrew (macOS)
After automatically updating Postgres to 9.6.1 via Homebrew, the pg_ctl start command didn't work.
The error was something like "database files are incompatible with server".
Database files have to be updated before starting the server, here are the steps that had to be followed:
# need to have both 9.6.1 and latest 9.5.x installed, and keep 9.6.1 as default
brew unlink postgresql
brew install postgresql95
brew unlink postgresql95
brew link postgresql
