Anyways, I am more interested in how PostgreSQL can make us have trailing zeroes or no trailing zeroes depending on the type you choose or other work-arounds.
avi_vallarapu··on [dead]
I think there is a way to get the inserted trailing zeroes in Oracle as well. So if you explicitly inserted 10.0500, you want to get 10.0500 but not 10.05 ?
