The locale settings influence the following SQL features:
- Sort order in queries using ORDER BY or the standard comparison
operators on textual data

...

Check that PostgreSQL is actually using the locale that you think it is.
The LC_COLLATE and LC_CTYPE settings are determined when a database is
created, and cannot be changed except by creating a new database.

So I assume this is not a bug in roundup or sqlite, but standard behaviour.

OK to close this?
