Hi,
I have a couple questions about how update, truncate and vacuum would
work together.
1) If I update a table foo (id int, value numeric (20, 6))
with
update foo set value = 100 where id = 1
Would a vacuum be necessary after this type of operation since the
updated value is a numeric? (as opposed to a sql type where its size
could potentially change i.e varchar)
2) After several updates/deletes to a table, if I truncate it, would
it be necessary to run vacuum in order to reclaim the space?
thanks,
Scott
