release() previously returned the connection to the pool in a finally even when the pg_advisory_unlock statement failed, so a pooled connection could be reused while its session still held the migration advisory lock - the next borrower would block every other runner (reviewer finding F4). On unlock failure the connection is now destroyed (client.release(error) removes the client from the pool, ending the session and its lock); the plain client.release() is kept only on the success path. Locked in by a static assertion, a mutation probe, and a deterministic stub-pool behavioral probe of the committed release() control flow.
