Look at the documentation here:

The upshot is that you should vacuum every table in the database at
least once every billion transaction. It doesn't have to be a VACUUM
FULL, just run VACUUM without specifying a table.
There's some info in there about how to work out when it is necessary.
Hope this helps,
