Exactly what I meant.

No, I just used the term lazy because that is how it is referred to
within the code. I'm happy that there are two kinds of vacuum, lazy and
full and that we differentiate between them by using the FULL keyword.
Forgive me if this is wrong, but I took that Alvaro was applying a
"reductio ad absurdum" argument (i.e. taking the piss). I laughed
heartily at the thought of LAZY becoming a PostgreSQL keyword.
Anyway, I think it shows how confusing the subject is when I can't
easily explain to you what I mean.
