Hi Laurenz
Thanks for your answer.
If I do not modify data on the subscriber side, the best practice will be to
not to define the column as identity or it is better to have subscriber's table
definition as close as possible to the publisher and leave it as identity?
Thanks

It does not really matter if you use "serial" or an identity column on the
logical standby or not. The sequence on the standby won't be advanced.
The best way to prevent conflicts from happening is *not* to modify the data on
the standby.
