GROUP BY error in getNodesHierarchyQueryBuilder method on PostgreSQL DBMS #109

[Biskabos]

Hello. Dear developers, please tell me how to solve the problem with ORDER BY on PostgreSQL. The error occurs only on this type of database and I do not know how to solve it correctly. If I remove ORDER BY, then my section structure and menu breaks. Version 2.0.2.
