+ID:          issue-7499
+ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7499
+TITLE:       Problem with restore
+DESCRIPTION: 
+    Test uses .fbk which was created on the basis of DDL from gh_7517_test.py
+    in FB 3.0.10.33665. There is stored procedure which has query that uses
+    inappropriate index.
+    Restore from this .fbk must finish with WARNING and display name of that index.
+NOTES:
+    [30.03.2023] pzotov
+    Unfortunately, I could not find DDL that leads not only to warning (on FB builds after fix)
+    but also to "gbak: ERROR" if we try to restore from this .fbk on FB builds *before* this
+    problem was fixed: 'gbak -rep' on all major FB just silently finished w/o any message.
