changed the title
Meaningful case-folding operations are used within the database for hashtags, so do not recommend using `C`, which would cause issues with non-ASCII hashtags.

I merged this swiftly because of mastodon/mastodon#14860 (comment) but I'm still not 100% happy: The warning will appear always with no way to dismiss it (and we decided that using C or POSIX collation isn't actually a good idea either) and then "Am I affected?" makes you go through two checks if you are not affected, one of which requires downtime. I can sense justified sysadmin frustration coming. |
