My opinion is exactly the opposite. Don't we already have a need
for error-safe type conversions, too, in the JSON stuff? Even if
I couldn't point to a need-it-now requirement, I think we will
eventually find a use for this with some other classes of functions.

I'm proposing *exactly* an extension of the elog.c interface;
so were you, a couple messages back. It's only specialized to I/O
in the sense that our current need is for that.
