Yeah, agreed.  The only consideration that'd make that a remotely
sane idea is that if somebody did the work, there would be other
uses for it.  (One that comes to mind immediately is cleaning up
ecpg's miserably-maintained fork of the backend datetime code.)

But there's no denying that it would be a large amount of work
(if it's even feasible), and nobody has stepped up to volunteer.
It's not reasonable to hold up this particular feature waiting
for that to happen.

If a tab-delimited file can handle this requirement, that seems
like a sane choice to me.
