  //Note that connection must be open
  PgSqlRowType pgRowType = PgSqlRowType.GetRowType("tperson", conn);
  PgSqlRow pgRow = pgRowType.Parse("(''Robert'',30)");
  //provide parameters to command and execute it
  pgCommand.Parameters.Add("ID",4);
  pgCommand.Parameters.Add("ROW",pgRow);
  pgCommand.ExecuteNonQuery();
  Console.WriteLine("Record added");
}

Visual Basic

Sub InsertDataWithParameters(ByVal conn As PgSqlConnection)
  Dim str As String = "INSERT INTO personnel VALUES (:ID, :ROW)"
  Dim pgCommand As PgSqlCommand = New PgSqlCommand(str, conn)
  'Create instance of PgSqlRow and fill with data
  'Note that connection must be open
  Dim pgRowType As PgSqlRowType = PgSqlRowType.GetRowType("tperson", conn)
  Dim pgRow As PgSqlRow = pgRowType.Parse("(''Robert'',30)")
  'provide parameters to command and execute it
