Question

由于此行python manage.py migrate

而运行ALTER TABLE wagtailcore_page ALTER COLUMN path TYPE VARCHAR(255) COLLATE "C"时出现此错误

https://github.com/wagtail/wagtail/blob/master/wagtail/wagtailcore/migrations/0001_squashed_0016_change_page_url_path_to_text_field.py#L130

我该如何解决？

更新

当然，这是：

您可能拥有一个早于9.1的PostgreSQL版本（2011年首次发布，现在已不再支持），当引入排序规则时。

解决方案是升级到更新版本的PostgreSQL。

“COLLATE”或附近的语法错误wagtail1.9 postgresql9.5.2
