Upgrade PostgreSQL 9.6.5 to 10.0 using Homebrew (macOS)
After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."
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.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install [email protected]
brew unlink [email protected]
brew link postgresql
