"vacuum" and "cluster"

Hello,

Does running "cluster" remove the need to run "vacuum"?

I get a feeling that since cluster is already physically reordering the
rows, it may as well remove the dead rows... no?

My second question is, if vacuum is still needed, does it matter whether
I run vacuum first or cluster first?

Here's our current weekly db maintenance routine:

1. vacuum full
2. cluster
3. reindex
4. analyze

Thanks,
Jimmy Choi
