        The configure script seems to prefer this version of Python over any others,
        so you may experience linker problems as described in:
          http://osdir.com/ml/pgsql-general/2009-09/msg00160.html

        To fix this issue, you may need to either delete the version of Python
        shown above, or move it out of the way before brewing PostgreSQL.

  def caveats
    s = <<-EOS.undent
    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/mxcl/homebrew/issues/issue/2510

    If this is your first install, create a database with:
      initdb #{var}/postgres -E utf8

    To migrate existing data from a previous major version (pre-9.2) of PostgreSQL, see:
      http://www.postgresql.org/docs/9.2/static/upgrading.html

    Some machines may require provisioning of shared memory:
      http://www.postgresql.org/docs/9.2/static/kernel-resources.html#SYSVIPC

  def gem_caveats; <<-EOS.undent
    When installing the postgres gem, including ARCHFLAGS is recommended:
      ARCHFLAGS="-arch x86_64" gem install pg

    To install gems without sudo, see the Homebrew wiki.
