Well, what we've avoided doing so far, on the assumption that we might
mask some subtle but important problem, is to run the select outputs
through a formatting function which strips off a few (in)significant
digits.
I'm not sure if to_char() can do the job (it seems to be oriented to
doing fixed-length fields) but if it can then we've got something usable
already.
