Haven't seen the original message, but it looks to me that
the column is declared as decimal with 4 digits after the
decimal point. Therefore, all values get rounded at the time
of INSERT/UPDATE. The above looks numerically right to me.
Isn't that behaviour correct? Does the standard define
something else?
