pgsql: Avoid tests which crash the calling process on Windows

Avoid tests which crash the calling process on Windows

Certain recovery tests use the Perl IPC::Run module's start/kill_kill
method of processing. On at least some versions of perl this causes the
whole process and its caller to crash. If we ever find a better way of
doing these tests they can be re-enabled on this platform. This does not
affect Mingw or Cygwin builds, which use a different perl and a
different shell and so are not affected.
