Why pgJDBC?
The PostgreSQL JDBC Driver allows Java programs to connect to a PostgreSQL database using standard, database independent Java code. pgJDBC is an open source JDBC driver written in Pure Java (Type 4), and communicates in the PostgreSQL native network protocol. Because of this, the driver is platform independent; once compiled, the driver can be used on any system.

One small fix to deal with all well known types in SimpleQuery mode
pgJDBC allows Java programs to connect to a PostgreSQL database using standard, database independent Java code.
pgJDBC provides a reasonably complete implementation of the JDBC specification in addition to some PostgreSQL specific extensions.
The current development driver supports eleven server versions and three java environments.
Processing a simple query
This example will issue a simple query and print out the first column of each row using a Statement.
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery("SELECT * FROM mytable WHERE columnfoo = 500");
while (rs.next()) {
System.out.print("Column 1 returned ");
System.out.println(rs.getString(1));
}
rs.close();
st.close();
