I don't really agree. For me manual and automated prewarming are pretty closely related. Sure they have their independent usages, and not too much code might be shared. But grouping them in the same extension seems to make sense, it's confusing to have closely related but independent extensions. > One point that seems to be worth discussing is when should the buffer > information be dumped to a file?

Should probably be at some regular interval - not sure if checkpoints are the best time (or if it's even realistic to tie a bgworker to checkpoints), since checkpoints have a significant impact on the state of shared_buffers.
