postgres block size alignment with filesystem block size
Hello, I am setting up a new postgres production server in a managed hosting environment. I dont have much insight into the underlying disk architecture but the filesystem I have been presented with has a 4k block size. Postgres defaults to 8k block size; would it be beneficial to repave the filesystem at an 8k block size or problematic to leave it at 4k? I have seen posts suggesting alignment of the postgres block size and the file system block size and the raid block size, but wonder if a multiple is sufficient or if it should match exactly.
