Versions are useful for figuring out if I should upgrade packages or
not. But I believe the extension framework has explicitly made the
"upgrade" problem a manual one at this point, either taking
destination versions from the control, or the alter command.
So for PGXN's problem, I see the point of versions being required.
But for installation the dependancy graph, "provides/features" rather
than versions are much more useful. And automatic feature/provides
(like library so, and symbol versions in the OS package world,
"objects" in PG world) would definitely be nice, but my Makefile can
build those for me for now until 9.2 (or 9.3, 9.3, etc), if only I had
a way to track them with my installed extension ;-) </stop begging>
