home: make sure users and group autocomplete is case insensitive Both SQLite and MySQL have a case-insensitive LIKE operator by default, but PostgreSQL does not. As a result, a query for 'john' does not match the user 'John Doe'. As case-insensitivity is most user-friendly in the context of autocompletion of users and groups, switch to the ilike() method of SQLAlchemy rather than like().
