About that list:  We need to define a new primary key for it.

For example, "Linux 2.2.x" is wildly inaccurate.  Red Hat probably works,
but maybe Caldera won't (true story).  Maybe 2.2.16-suse-patches works but
2.2.14 won't (true story).  The glibc version is probably equally (if not
more) important as the kernel version.  So in matters Linux I think we
need to list the name and version of the distribution as it shows on the
box.

We also need to keep track of the compiler used.  I've had situations
where gcc 2.8.1 didn't work on an otherwise normal Linux box.  We've also
listed Solaris as supported although it was provably impossible to build
PostgreSQL with the native compiler.

I'd suggest a couple of concrete points to watch for before the upcoming
release:

1.  Use the config.guess output as the primary way to index supported
    platforms.  This will make maintaining the build system much easier.

2.  If there are several vendors that ship this system, also record the
    name by which you'd ask for your system in the store.

3.  If you didn't use the compiler (or other binutils) that came with your
    system, record that.

4.  Only list as supported actual systems from which you have actual
    reports, no "3.x".
