title: PostgreSQL recompile needed after upgrading to a quad-core CPU?
body: <p>I recently upgraded my server running CentOS 5.0 to a quad-core CPU from a dual-core CPU. Do I need a recompile to make use of the added cores? PostgreSQL was installed by compiling from source.</p>
  
  <p>EDIT: The upgrade was from an Intel Xeon 5130 to an Intel Xeon 5345.</p>
