Note that previously empty strings were treated as zero, not null (unlike
when using Oracle) when used for numeric values.

It is hard to give you concrete advice without knowing more about how
the data is collected. But having the application emit NULL or '0' (depending
on which you want) instead of '' is probably the way you want to go (if you
can). If you are using COPY, then there is a way to say that the empty
string represents a NULL.
