добрые люди из Stack Overflow.
Я пытался перенести очень старую установку MediaWiki из MySQL в базу данных Postrgre SQL, но зашел в тупик. Текущая версия - 1.26.1. К сожалению, целостность базы данных не может быть гарантирована, потому что wiki была создана еще в 2012 году, и все таблицы db работают на движке MyISAM.
Основная цель - поместить все в docker с PostgreSQL при сохранении всего содержимого MediaWiki, авторов и истории страниц.
Я создал локальную копию базы данных и MediaWiki на своем локальном компьютере и успешно обновился до версии 1.34 (с обновлением . php скрипт). Затем я попробовал:
1. Загрузите db с помощью pgloader
pgloader успешно перенес MySQL db в PostgreSQL. Настроил $wgDBmwschema. update.php вылетает.
./update.php

С другой стороны, вики загружается. К сожалению, кодировка неверна, что делает всю Wiki нечитаемой и разрывает ссылки.

Too many loops!
Я пытался получить дополнительную информацию из самого сценария , но я не человек Perl.
Я также попытался выяснить, каковы циклы внешнего ключа в базе данных, но, поскольку все таблицы работают на MyISAM, внешних ключей нет вообще.
Любые предложения о том, как действовать для достижения Главная цель?
