# Add default order to the query in order to avoid random PostgreSQL
# ordering between the queries for different pages of results. If some of
# the queried records are updated or new records are added between the
# API calls to different pages of records, PostgreSQL can randomly change
# the order causing duplicates to appear or some records to disappear from
# the results unless the order of the records is explicitly defined.
#
# Note that this needs to be called as the last method before returning
# the query so that it won't affect the desired ordering specified in the
# GraphQ query. In that case, ordering by ID will be the secondary order
# of the records.
