[Dovecot] A questions about consume_results (driver-pgsql.c)

Code

static void consume_results(struct pgsql_db *db) { do { if (!PQconsumeInput(db->pg)) break;

	if (PQisBusy(db->pg))
		return;
} while (PQgetResult(db->pg) != NULL);

if (PQstatus(db->pg) == CONNECTION_BAD)
	io_remove_closed(&db->io);
else
	io_remove(&db->io);

db->querying = FALSE;
if (db->queue != NULL && db->connected)
	queue_send_next(db);

}

This is the only part of the driver-pgsql.c code where a CONNECTION_BAD does not result in driver_pgsql_close being called. This will likely happen after the next query (from queue or a new one) failed because the connection was bad. Is there a reason for this?
