Hello,
We noticed the constraint in 
   utils/kamctl/postgres/usrloc-create.sql
is broken, causing only 1 user location ever to be saved because server_id is always 1 and connection_id is always -1

We had to remove the constraint to fix the issue.
This is the specific line inside the CREATE TABLE

    CONSTRAINT location_connection_idx UNIQUE (server_id, connection_id)

Thanks,
Emmanuel
