I dug around a little and found that we had turned on vacuum cost
limits on the central databases, because otherwise the web team
complained about performance during maintenance windows.  On the
county database we generally don't have users working all night, so
we do maintenance during off hours, and run without cost-based
limits.
 
When the full run completes, I'll try analyze on that table again,
in a session with the limits off.
 
Maybe vacuumdb should have an option to disable the limits, and we
recommend that after pg_upgrade?
