It's not clear to me why we have width_bucket operating on numeric and
not float8 --- that seems like an oversight, if not outright
misunderstanding of the type hierarchy. But if we had the float8
version, I think Jeremy's problem would be solved just by applying
the float8 version to "extract(epoch from timestamp)". I don't really
see the use-case for putting N versions of the function in there.
