Honestly I don't know much about this but I think this can occur because PHP (or more specifically, the PDO extension) isn't necessarily aware of the health of the PostgreSQL node it's connected to. From PHP's perspective, it opened a connection, and unless explicitly told otherwise, it will assume the connection remains open. The Patroni switchover/failover is happening independently of PHP. PgBouncer is probably a good solution for this.
If I knew how to invalidate failed connection in the persistent pool, that would be enough.
