Mapping Java BigDecimal

Hi All,

We decide add support PostgreSQL database (now supporting only Oracle
database) to our product.

In Oracle we mapping Java BigDecimal to number(19, 2), in PostgreSQL to
numeric(19, 2).

If I store to "BigDecimal column" number without decimal, e.g. "3", than
Oracle JDBC driver return "3", but PostgreSQL JDBC driver return "3.00".

Is there some way (mapping, server setup, jdbc driver setup,...) how
reach return number without trailing zeroes on decimal position?

I'm using JDBC4 PostgreSQL Driver (v. 8.4-701) and PostgreSQL v. 8.1.18
(default for CentoOS 5.3).
Thank you all
