Thank you for looking into this, I went back and forth on the name, and
mistyped it a few times.

ICU seems to use "foldcase":

https://unicode-org.github.io/icu-docs/apidoc/dev/icu4c/ucasemap_8h.html

and it seems to be slightly more proper grammatically (with "fold"
being the verb). However, "case folding" is common terminology in
Postgres and Unicode, so "casefold" can be seen as the verb instead.

I don't have a strong opinion here so I will just go with whatever
seems like the popular choice.

Regards,
