Hi,
it happens even on Intel, it's not an architecture problem. The
problem is that dbbind does not take into consideration source
precision/scale. I'm going to improve dbbind (and perhaps add
dbbind_ps) in order to make possible to support copying numeric
entirely with precision/scale based on the source.
