Fear.
Maybe eventually, but right now I think it's too risky.
One point that I already found out the hard way is that sizeof(off_t) = 8
does not guarantee the availability of largefile support; there can also
be filesystem-level constraints, and perhaps other things we know not of
at this point.
I think this needs to be treated as experimental until it's got a few
more than zero miles under its belt. I wouldn't be too surprised to
find that we have to implement it as a run-time switch instead of
compile-time, in order to not fail miserably when somebody sticks a
tablespace on an archaic filesystem.
