// TODO: previous_reference_sha256 was NOT NULL before but it broke sytest because
// sytest sends no SHA256 sums in the prev_events references in the soft-fail tests.
// In Postgres an empty BYTEA field is not NULL so it's fine there. In SQLite it
// seems to care that it's empty and therefore hits a NOT NULL constraint on insert.
// We should really work out what the right thing to do here is.
