The following bug has been logged online:

Bug reference:      1712
Logged by:          Gilles Dubochet
Email address:      dubochet@urbanet.ch
PostgreSQL version: 8.0.2
Operating system:   Linux
Description:        JDBC column precision for bigint is 0
Details:

Whith the JDBC driver at least up to version 8.1dev-400, the result of the
getPrecision method of ResultSetMetaData on a bigint column is 0 instead of
the expected 19.

Code seems to be missing in
org.postgresql.jdbc2.AbstractJdbc2ResultSetMetadata after line 359 (in
source code 8.1dev-400).

Java code to reproduce problem:
import java.sql.*;
public class Main {
    public static void main(String[] args) throws Exception {
        Class.forName("org.postgresql.Driver");
        Connection con =
DriverManager.getConnection("jdbc:postgresql://localhost/pguser", "pguser",
"");
        Statement stmt = con.createStatement();
        stmt.execute("DROP TABLE mytable");
        stmt.execute("CREATE TABLE mytable (bi BIGINT)");
        System.out.println("We get "+
            stmt.executeQuery("select * from
mytable").getMetaData().getPrecision(1)+
        " but should get 19");
    }
}
