The SqlStatementExecutor disposes DbCommands and closes the connection before the DbDataReader can be consumed.

• Update pipeline uses a Consume(DbDataReader) pattern that could be provided as an Action<T> allowing the executor to control the life-cycle of the ADO objects
• Query
  • Requires a streaming / lazy reader, calling Dispose and closing connection outside of the executor
  • Reads need to be performed by an IValueBufferFactory to ensure proper typed / untyped reads occour
    • In FromSql case, requires access to DbDataReader before IValueBufferFactory can be constructed
