Commit 943aa38564c tries to address a performance issue in the display and
search of extended patron attributes during overdue notice generation by
disabling a feature that had been sponsored by a library (added in commit
ab44e2986a0).

On initial glance, adding additional indexes to authorised_values,
borrower_attributes, and borrower_attribute_types should improve the
performance of the query.

Note to all re regarding 943aa38564c: if you find a performance problem, please
don't simply disable a feature - please fix the actual problem.  The
performance issue is real, hence I'm marking this as a blocker for 3.2.
