title: rails - postgres error: Reason: Incompatible library version: libpq.5.dylib requires version 1.0.0 or later,
body: <p>I am stuck with the setup of Ruby (1.9.3), Rails and Postgres  (9.0.8) on my Mac (10.6.8).
  Everytime when I run <code>rails console</code> I get the following error:</p>

  <p>I really don't know how to fix this. I already tried installing a different Postgres version and I still get the same error.</p>
