It's explicitly documented to be this way. And I think it has to work this way for recovery to work. I think the reason you and Bharath and Andres are talking past each other is that they're thinking about how the implementation works and you're talking about the API definition. If you read the API definition and treat the functions as a black box I think you're right -- those two definitions sound pretty much equivalent to me. They both extend the file, possibly multiple blocks, and zero fill. The only difference is that smgrextend() additionally allows you to provide data. -- greg
