An unfortunate typo in commit 2d819a08a1 can cause wrong results when the default collation provider is libc, LC_CTYPE=C, and LC_COLLATE is a real locale. Users with this combination of settings must REINDEX all affected indexes. The same typo can also cause performance degradation when LC_COLLATE=C and LC_CTYPE is a real locale. Problem does not exist in master (due to refactoring), so fix only in version 17. Reported-by: Drew Callahan Discussion: https://postgr.es/m/d5081a7f4f6d425c28dd69d1e09b2e78f149e726.camel@j-davis.com
