To Reproduce
Steps to reproduce the behaviour:

Error seen after upgrading to 42.2.9. No error seen with 42.2.8.

Attempts to register an Out callable parameter do not work. See example code (confidential bits masked out) and error:

    CallableStatement cs = null;
    Connection conn == null;
    ResultSet rs = null;

    try {

        conn = getConnection();
        cs = conn.prepareCall("{ ? = call xxxx.yyyy (?,?,?,?)}");

        cs.registerOutParameter(1, Types.REF_CURSOR);

        cs.setLong(2, aaaa);
       
        cs.setLong(3, bbb);
        

        cs.setLong(4, cccc);
       
     
        cs.setNull(5, Types.NUMERIC);

Exception thrown at the last step:

Caused by: org.postgresql.util.PSQLException: The column index is out of range: 5, number of columns: 4.”
78: ” at org.postgresql.jdbc.PgPreparedStatement.setNull(PgPreparedStatement.java:188)”

Somehow the out parameter is not registering properly now. Works well in the previous 42.2.8 (and other previous releases). If syntax of the SQL needs to change anyhow, please advise.
