+ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7718
+TITLE:       Allow to create database with different owner
+DESCRIPTION:
+    Test runs 'CREATE DATABASE' with specifying OWNER clause with temporary user who has no any privilege.
+    Then we try to connect to just created database by this user.
+    He must OWNER of this DB and thus have ability to run any DDL there (only 'create table' is checked).
+    Finally, this user must be able to DROP database.
+NOTES:
+    Checked on 6.0.0.139
