Log message:
    When testing usability of a partial index, recognize that an index
    predicate of the form 'foo IS NOT NULL' is implied by a WHERE clause
    that uses 'foo' in any strict operator or function.  Per suggestion
    and preliminary implementation by John Siracusa; some further hacking
    by moi.
