I changed second statement to

INSERT INTO session ('MYCOMPNAME',ipaddress,logintime,loggeduser)
   SELECT 'MYCOMPNAME',
inet_client_addr()::CHAR(14),current_timestamp::CHAR(28),CURRENT_USER
         WHERE NOT EXISTS (SELECT 1 FROM session WHERE
workplace='MYCOMPNAME')

where MYCOMPNAME is logging-in computer name.

Will this fix the isse or is it better to wait 100 ms  and re-try insert?
