You could implement an optimistic lock strategy by placing a 'version'
column in the table and increment it on successful 'check-out' and test
against the value the user has as he/she tried to act on the record. If
some else got there first the second user fails to check-out the queue
item. Trigg

and then delete the rows. pg_try_advisory_lock is used to (attempt
to) stop two workers from doing the same job.
