    If builds of PostgreSQL are failing and you have a prior version installed,
    you may need to remove the previous version first. See:
      https://github.com/Homebrew/homebrew/issues/2510

    To migrate existing data from a previous major version (pre-15.x) of PostgreSQL, see:
      https://www.postgresql.org/docs/15/upgrading.html
