Seems reasonable to me. Obviously I'd mixed up the datetime/time_t
issues I ran into previously, so having the configure options as well
would be largely useless.

That said, is zlib used by toast or do we have some other code for
that? If it is used for that, do we record it's presence or absence in
pg_control?
