Rename post_update_add_hierarchy_processor

The post-update was not executed after updating the module to 2.0.6. So we changed the hook name from facets_post_update_8001_8001_8001_8001_8001_8001_8001_8001_add_hierarchy_processor to facets_post_update_8001_add_hierarchy_processor as in 3.x https://git.drupalcode.org/project/facets/-/blob/3.0.x/facets.post_updat... & fixed the issue.

Patch in #4 worked for me. Sure would be nice to get this into an official release.

facets 8001_add_hierarchy_process post-update Add the hierarchy processor to facets that have the hierarchy

Restating since I updated the previous comment. #2 works for me and follows Drupal documentation for hook_post_update_NAME.

I think this is a good idea if we would've seen this closer to when this was added, since it has been a while now, I think it will only lead to trouble and it just a cosmetic fix. I think therefor we should just won't fix this issue.
