+ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7168
+TITLE:       Ignore missing UDR libraries during restore
+DESCRIPTION:
+    Database with 3d-party UDR was created beforehand in FB 4.0.1, backed up and .fbk was compressed.
+    After decompressing .fbk we try to restore this database using FB snapshot which for sure has no
+    such UDR, with verbose = True.
+    Test verifies that restore log contains messages about UDR and correct finish of restoring process.
+NOTES:
+    [02.03.2023] pzotov
+    Confirmed problem on 4.0.1.2707 (21-jan-2022), 5.0.0.471 (09-apr-2022): restore fails with error
+    "firebird.driver.types.DatabaseError: UDR module not loaded" and message after it that can be in localized.
+    Checked on: 4.0.3.2904, 5.0.0.475 -- all OK.
