Agreed. However, I think that if PostgreSQL has support for numerics of
1000 characters, it might make sense for it to have the operators to
ensure that operations exist for most if not all common mathmatical
operations, especially since many esoteric math functions could make use
of such accuracy.
I wonder what Joe Conway's take on all this would be, since he's the guy
that made PL/R a reality.
I don't think we should include anything that could be added either. U
just don't like surprises, which is what I consider it when I raise one
numeric to another numeric and get a floating point answer.
