ISSUE:       4729
TITLE:       Grant and Revoke update (field) [CORE4407]
NOTES:
    [16.02.2023] pzotov
    Confirmed bug on 5.0.0.843, 4.0.3.2876, 3.0.11.33639 - got:
        Statement failed, SQLSTATE = 28000
        no permission for UPDATE access to COLUMN TEST.AGE
    Checked on 5.0.0.938, 4.0.3.2900, 3.0.11.33664 -- all fine
    ::: NOTE :::
    If script is executed from command line using ISQL then problem looks as described in the ticket.
    But if the same script is executed from firebird-qa then FB 5.0.0.843 crashes.
