I had the same problem. It's a backend problem, not JDBC related. If you
try to "select val2 from test where val1=123.45" in a table defined as
"create table test (val1 numeric, val2 int)" in psql or any other
frontend you will have the exact same problem.
I was told that this would be fixed in PostgreSQL 7.3, but I don't have
a 7.3 server to check if it was fixed or not.
Bottom line: use an explicit cast. That's how we solved it. BTW, you
need to use explicit casts anyway if you want the server to use indices.
Hope this helps,
