+## Restore a production dump
+
+To replace the development database with a production SQL dump:
+
+```bash
+bin/rails db:drop db:create
+
+gzip -dc ../registry-YYMMDD.sql.gz \
+  | sed 's/OWNER TO registry;/OWNER TO registry_test;/g' \
+  | bin/rails db
+
+bin/rails db:migrate
+```
+
+The ownership replacement is needed because production objects belong to the
+`registry` Postgres role, while development uses `registry_test`.
