"invenio_2013_08_22_hstRECORD_affected_fields" upgrade recipe executes:
ALTER TABLE hstRECORD ADD COLUMN affected_fields text NOT NULL default '' AFTER job_details
The upgrade script gives a warning that "BLOB and TEXT columns cannot have DEFAULT values".
Although probably not important to the table's functionality, you could try removing/changing default '' to suppress the warning...
