  def caveats; <<~EOS
    If builds of PostgreSQL 9 are failing and you have version 8.x installed,
    you may need to remove the previous version first. See:
      https://github.com/Homebrew/legacy-homebrew/issues/2510

    To migrate existing data from a previous major version (pre-9.0) of PostgreSQL, see:
      https://www.postgresql.org/docs/9.5/static/upgrading.html

    To migrate existing data from a previous minor version (9.0-9.4) of PostgreSQL, see:
      https://www.postgresql.org/docs/9.5/static/pgupgrade.html

      You will need your previous PostgreSQL installation from brew to perform `pg_upgrade`.
      Do not run `brew cleanup postgresql@9.5` until you have performed the migration.
