TITLE:       Dropping FK on GTT crashes server
DESCRIPTION:
JIRA:        CORE-4212
FBTEST:      bugs.core_4212
NOTES:
    [05.10.2023] pzotov
    Confirmed crash on 3.0.0.30566 Alpha1.
    Removed SHOW command. It is enough for this test just to try to insert record in the 'T2' table after dropping FK.
