What is the impact of this newly isolated ANALYZE command on the need
and/or frequency for VACUUMs?
I'd like to reduce the frequency of VACUUMs given my understanding has
been that updates/inserts/deletes are a no-no during VACUUMs (that was
6.5.x era hearsay), and we lock people out during VACUUMs (VACUUM
ANALYZE, that is).
