I'm not really sure about that.

Maybe we should separate all that, e.g.,

SELECT version(); => 'PostgreSQL 8.4devel'
SELECT pg_host_os(); => 'bsdi4.3.1'
SELECT pg_host_cpu(); => 'i386' (although this is still faulty, as per my
original argument; needs some thought)
SELECT pg_compiler(); => 'GCC 2.95.3'
SELECT pg_pointer_size(); => 4 (or 32) (this could also be a SHOW variable)
