Hi,
I was just wondering over it. This is for difference between vacuum full and
vacuum analyze. Can somebody enlighten,
1. IIRC vacuum recovers/reuses dead tuples generated from update but can not do
so for delete? Why?
2. Vacuum full locks entire table, is it possible that it locks a page at a
time and deal with it. It will make vacuum full non-blocking at the cost of
letting it run for a longer time. Or is it that the defragmentation algorithm
needs more than a page?
Just a thought..
