I thought that adding an ANALYZE would make the test be net slower, not
faster; ANALYZE isn't free, even on just a row or so.  Also, I believe
that coding the test this way makes the leader send the param values to
multiple workers, which would flush out any problems with serializing a
value multiple times.  As against that, there's a hazard that the number
of workers might not be stable ... but it seems like we have lots of
other occurrences of that same hazard elsewhere in this test script.
