Errors in sending a message after upgrading from 1.10 or 15.04 to master

Version: master (15.10)
Browser: any
Platform: apache 2.x, php 5.x and PostgreSQL

After upgrading the database from 1.10 or 15.04 to current master (including the patch which changes multirecipientnotification from artefact to module). I got the following errors when sending a message (htdocs/module/multirecipientnotification/sendmessage.php):

[WAR] b5 (lib/errors.php:747) Failed to get a recordset: postgres8 error: [-18: ERROR: relation "module_multirecipient_notification_id_seq" does not exist
LINE 1: SELECT NEXTVAL('module_multirecipient_notification_id_seq')
                      ^] in EXECUTE("SELECT NEXTVAL('module_multirecipient_notification_id_seq')")
Command was: SELECT NEXTVAL('module_multirecipient_notification_id_seq')
