Just wanted to make sure that by tuple-level we mean the same thing.

When saying tuple-level do you mean that the entire tuple should be
compressed as one large binary (i.e. similarly to page-level
compression but more granularly), or every single attribute should be
compressed separately (similarly to how TOAST does this)?
