I don't know about the settings you mention, but a frequent vacuum
does not at all obviate a vacuum full. My database is vacuumed every
night, but a while ago I found that a vacuum full changed a simple
single-table query from well over 30 seconds to one or two. We now
do a vacuum full every night.
