- repair a regression caused by #3282, where we no longer were
applying any topological sort to tables on SQLite. See the
changelog for details, but we now continue to sort
tables for SQLite on DROP, prohibit the sort from considering
alter, and only warn if we encounter an unresolvable cycle, in
which case, then we forego the ordering. use_alter as always
is used to break such a cycle.
fixes #3378
