The rounding when you dump it out is going to be consistant though, is
it not? I mean, you might get a difference between what you try to set
it to and the result that you get from pg_dump, but if you compare one
pg_dump to another done later there shouldn't be any change, right? If
there is an architecture difference then I could maybe see it, but I
thought float-handling was well-defined on systems we run on.
