My, you *are* paranoid about float4 aren't you? Once you've stored
a given value, it's always going to dump the same. Diffing different
dumps isn't going to be a problem. I concede that it might look
different from what you put in originally, but we make no effort to
guarantee that for DDL anyway.
(It is true that with pg_dump's default float_extra_digits setting,
outputs from this column might look uglier than they need to.
I don't see anything wrong with having pg_dump forcibly round the
value to five or so digits, though.)
