    syntax for all set flaggers. If you specify SET FLAGGER ON, which
    is equivalent to SET FLAGGER SQL92_ENTRY ON, the SHOW FLAGGER
    statement informs you that flagging for the ANSI/ISO standard
    is set. If you specified SET FLAGGER MIA ON, the SHOW FLAGGER
    statement informs you that flagging for the MIA standard is set.
