Bug 1013341

Description of problem:

upgrade script  03_03_0710_add_profile_to_network_interface.sql has the following code :

--START--

Create or replace FUNCTION __temp_has_port_mirroring_vm_interfaces(v_network_id UUID) RETURNS BOOLEAN
   AS $procedure$
BEGIN
   RETURN ((SELECT 1
   FROM vm_interface
   INNER JOIN vm_static
   ON vm_static.vm_guid = vm_interface.vm_guid
   INNER JOIN network_cluster
   ON network_cluster.cluster_id = vm_static.vds_group_id
   INNER JOIN network
   ON network.id = network_cluster.network_id
   AND network.name = vm_interface.network_name
   WHERE network.id = v_network_id
   AND port_mirroring = TRUE) IS NOT NULL);
END; $procedure$
LANGUAGE plpgsql;

--END--

When this function is called, it expects to return one value which is boolean.
On the attached database more than one row is returned and breaks the upgrade as you can see in the log:

psql:upgrade/03_03_0710_add_profile_to_network_interface.sql:80: ERROR:  more than one row returned by a subquery used as an expression
CONTEXT:  SQL statement "SELECT  ((SELECT 1 FROM vm_interface INNER JOIN vm_static ON vm_static.vm_guid = vm_interface.vm_guid INNER JOIN network_cluster ON network_cluster.cluster_id = vm_static.vds_group_id INNER JOIN network ON network.id = network_cluster.network_id AND network.name = vm_interface.network_name WHERE network.id =  $1  AND port_mirroring = TRUE) IS NOT NULL)"
PL/pgSQL function "__temp_has_port_mirroring_vm_interfaces" line 2 at RETURN
