After studying the existing doc in more detail, I've come round to
agreeing with Peter and Chris' position that the existing table no
longer serves any useful purpose.  The interesting part of it is an
indication of which OSes and CPUs we support in general, but that can
be summarized in a few lines, with a pointer to the buildfarm for
concrete details.  Accordingly I've replaced the section with the
attached text.

 <sect1 id="supported-platforms">
  <title>Supported Platforms</title>

  <para>
   A platform (that is, a CPU architecture and operating system combination)
   is considered supported by the <productname>PostgreSQL</> development
   community if the code contains provisions to work on that platform and
   it has recently been verified to build and pass its regression tests
   on that platform.  Currently, most testing of platform compatibility
   is done automatically by test machines in the
   <ulink url="http://buildfarm.postgresql.org/">PostgreSQL Build Farm</ulink>.
   If you are interested in using <productname>PostgreSQL</> on a platform
   that is not represented in the build farm, but on which the code works
   or can be made to work, you are strongly encouraged to set up a build
   farm member machine so that continued compatibility can be assured.
  </para>

  <para>
   In general, <productname>PostgreSQL</> can be expected to work on
   these CPU architectures: x86, x86_64, IA64, PowerPC,
   PowerPC 64, S/390, S/390x, Sparc, Sparc 64, Alpha, ARM, MIPS, MIPSEL, M68K,
   and PA-RISC.  Code support exists for M32R, NS32K, and VAX, but these
   architectures are not known to have been tested recently.  It is often
   possible to build on an unsupported CPU type by configuring with
   <option>--disable-spinlocks</option>, but performance will be poor.
  </para>

  <para>
   <productname>PostgreSQL</> can be expected to work on these operating
   systems: Linux (all recent distributions), Windows (Win2000 SP4 and later),
   FreeBSD, OpenBSD, NetBSD, Mac OS X, AIX, HP/UX, IRIX, Solaris, Tru64 Unix,
   and UnixWare.  Other Unix-like systems may also work but are not currently
   being tested.  In most cases, all CPU architectures supported by
   a given operating system will work.  Look in the <filename>doc/</>
   directory of the source distribution to see if there is a FAQ document
   specific to your operating system, particularly if using an older system.
  </para>

  <para>
   If you have installation problems on a platform that is known
   to be supported according to recent build farm results, please report
   it to <email>pgsql-bugs(at)postgresql(dot)org</email>.  If you are interested
   in porting <productname>PostgreSQL</> to a new platform,
   <email>pgsql-ports(at)postgresql(dot)org</email> is the appropriate place
   to discuss that.
  </para>
