psql -U postgres with no -d restores into the 'postgres' maintenance database unless the app DB happens to carry that name. Fourth required argument passes -d <db-name>; ON_ERROR_STOP=1 so a mid-stream failure aborts instead of half-restoring silently. Found by the prod-migration plan final review (finding #6); drilled in Task 9 before cutover day. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
