Thank you for the report!
The issue is that the commit in master was dependent on a refactoring
patch, which allowed pg_strfold() to work on any pg_locale_t object,
even if ctype_is_c. Version 18 doesn't have that commit, so it crashed.
It seems to be fine in master, and it was only backported to 18, so the
attached patch is only intended for REL_18_STABLE.
