Thanks to all who responded.  I vacuumed out foo, and sure enough 
the select time is down to 10 seconds again.

I see in the docs the suggestion: 

    We recommend that active production databases be VACUUMM-ed nightly

Is this how people tend to do their vacuuming?  Does anyone do programmatic
vacuums instead of / in addition to a nightly run?  Is vacuuming mainly
necessary after big deletes, or are there other common situations 
requiring it?
