Yes, I have both DB systems running on my CentOS 5 desktop and have been 
running both together for many years.  The two servers listen on different 
ports/sockets and use separate database files, etc.  I would imagine one could 
also run Oracle at the same, but since I don't have an Oracle or really any 
reason to run it, I don't know for sure.

It does help to have enough resources available (eg enough RAM, diskspace, CPU 
cycles, etc.) for the databases to work well together.  (MySQL is somewhat 
MORE of a memory pig than PostgreSQL.)
