Hi Andreas, On the mailing list, I've noticed this patch. I tested its functionality and it works really well. I have a few minor, non-critical comments to share. In the `pg_ucasemap_open` function, the error message `casemap lookup failed:` doesn't seem ideal. This is because we're opening the `UCaseMap` here, rather than performing a "lookup" operation. In the comment `Additional makes sure we get the right options for case folding.`, the word Additional seems inappropriate ?? `Additionally` would be a better replacement.
