# Fully reset the test schema BEFORE restoring. `pg_dump --clean` only drops the
# objects that exist in PROD, so anything created on the test DB by a previously
# applied UNRELEASED migration (e.g. crewing tables/types/enum values not yet in
# prod) would survive as a leftover — and then collide with the `migrate deploy`
# replay below ("type already exists", P3009), blocking every later migration.
# Dropping the schema first guarantees the restore brings exactly prod's objects
# and the unreleased migrations apply cleanly. (No-op on an already-empty DB.)
