i'm sorry.  i had been under the mistaken impression that the vacuumdb
command updated the table/index statistics.  i returned to looking
through the manual after sending the email and almost immediately
stumbled upon the 'vacuum analyze' command.  sigh.  it optimizes as
expected now and returns in a proportionate amount of time.
