# Zulip has always had case-insensitive matching for email
# addresses on UserProfile objects. But Django's
# unique_together feature only supports case-sensitive
# indexes. So we reply the old unique_together index with a
# new case-insensitive index.
#
# Further, when we created the delivery_email field, we
# neglected to create an unique index on (realm_id,
# delivery_email), which meant race conditions or logic bugs
# could allow duplicate user accounts being created in
# organizations with EMAIL_ADDRESS_VISIBILITY_ADMINS. We
# correct this by adding the appropriate unique index there as
# well.
