Oh, I don't know.  Many applications require compiling for a target
architecture; SQL Server, for example, won't use a 2nd processor without
re-installation.   I'm not sure about Oracle.

It certainly wasn't too long ago that Linux gurus were esposing re-compiling
the kernel for the machine.

And it's not like they would *have* to re-compile to use PostgreSQL after
adding an additional processor.  Just if they wanted to maximize peformance
benefit.

Also, this is a fairly rare circumstance, I think; to judge by my clients,
once a database server is in production nobody touches the hardware.
