code: private void bindString(int paramIndex, String s, int oid) throws SQLException {
      preparedParameters.setStringParameter(paramIndex, s, oid);
    }
docs: This version is for values that should turn into strings e.g. setString directly calls
  bindString with no escaping; the per-protocol ParameterList does escaping as needed.
  
  @param paramIndex parameter index
  @param s value
  @param oid type oid
  @throws SQLException if something goes wrong
