Also, the last time I saw that tool, it output recommendations for
work_mem that I would never, ever recommend to anyone on a production
server - they were VERY high.

More generally, Josh has made repeated comments that various proposed
value/formulas for work_mem are too low, but obviously the people who
suggested them didn't think so.  So I'm a bit concerned that we don't
all agree on what the end goal of this activity looks like.
