+ID:          trigger.database.trigger_on_disconnect_03
+TITLE:       ON DISCONNECT trigger must fire if attachment is deleted from MON$ATTACHMENTS by another attachment.
+DESCRIPTION: 
+    Improvement was introduced 06-apr-2023, commit:
+    https://github.com/FirebirdSQL/firebird/commit/d64868cdcd91450e3c58aa9bfa9c1090912ac358
+    Test creates table 'detach_audit' which is fulfilled from ON DISCONNECT trigger if current user not SYSDBA.
+    We create non-privileged user ('tmp_worker') and make connection to database.
+    During that, we  create 'admin' connection which issues 'DELETE FROM MON$ATTACHMENTS WHERE ...'
+    This *must* cause firing trigger with adding record to 'detach_audit' table (and, according to doc, engine
+    always starts autonomous transaction for that).
+    Finally, we check that table 'detach_audit' has ONE record (containing name of non-priv user).
+NOTES:
+    [28.02.2023] pzotov
+    Confirmed missed trigger firing on 5.0.0.459 (05-apr-2023): table 'detach_audit' remained empty.
+    Checked on 5.0.0.961 - all OK.
