// After that change, there is a single global order which can only be
// changed by administrators.

// This migration removes the rows which store individual reordering and
// disabling of queries. If a user had reordered queries in such a way that
// a builtin query was at the top of the list, we try to write a preference
// which pins that query as their default to minimize disruption.
