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
isbetter 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
standbywon't be advanced.
The best way to prevent conflicts from happening is *not* to modify the data on the standby.
