In a second version of this patch posted on 2002-06-26 you can control
the tuple format by #define/#undef PG72FORMAT.  While there have been
voices saying that exposing this choice to the user viaconfigure --enable-pg72format
is not a good idea [well, it was one voice and the idea was called
"really, really bad" ;-) but the argument is still valid], I wonder
whether we shouldn't apply this second version (without the configure
parts) and put all forthcoming format changes under #ifndef
PG72FORMAT.

This way you can decide to go back to v7.2 format immediately before
going beta, if the changes are too hot to handle.  And I think if I
wouldn't volunteer to cleanup the #ifdef PG72FORMAT stuff after the
new format has been accepted, I would be nominated to do it ...
