I can't think of an easy way.  But you can always make your own type I guess.

Sadly, the people who have burdened you with this problem don't seem
to have fully understood the implications of rounding and the SQL
specification's take on when it happens.

Can you not even just make it wider?  I mean, pgsql can change types
on the fly, and since the value's will fit in newer, wider numerics,
then you have an easy solution.

Anything else you do is going to far more invasive than changing the schema.

Or you'll have to handle all this in code somewhere.
