    # On 64-bit systems, we need to look for a 32-bit Framework Python.
    # The configure script prefers this Python version, and if it doesn't
    # have 64-bit support then linking will fail.

      opoo "Detected a framework Python that does not have 64-bit support in:"
      puts <<-EOS.undent
          #{framework_python}

        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.

        Note that a framework Python in /Library/Frameworks/Python.framework is
        the "MacPython" verison, and not the system-provided version which is in:
          /System/Library/Frameworks/Python.framework

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

To build plpython against a specific Python, set PYTHON prior to brewing:
  PYTHON=/usr/local/bin/python  brew install postgresql
See:
  http://www.postgresql.org/docs/9.0/static/install-procedure.html


If this is your first install, create a database with:
  initdb #{var}/postgres9

If this is your first install, automatically load on login with:
  mkdir -p ~/Library/LaunchAgents
  cp #{prefix}/org.postgresql.postgres.plist ~/Library/LaunchAgents/
  launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist

If this is an upgrade and you already have the org.postgresql.postgres.plist loaded:
  launchctl unload -w ~/Library/LaunchAgents/org.postgresql.postgres.plist
  cp #{prefix}/org.postgresql.postgres.plist ~/Library/LaunchAgents/
  launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist

Or start manually with:
  pg_ctl -D #{var}/postgres9 -l #{var}/postgres9/server.log start

And stop with:
  pg_ctl -D #{var}/postgres9 stop -s -m fast


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

    if MacOS.prefer_64_bit? then
      s << <<-EOS

If you want to install the postgres gem, including ARCHFLAGS is recommended:
    env ARCHFLAGS="-arch x86_64" gem install pg

To install gems without sudo, see the Homebrew wiki.
