Hi all,
now this should be trivial, but I cannot udnerstand what is the
purpose of session_replication_role
<https://www.postgresql.org/docs/10/static/runtime-config-client.html#GUC-SESSION-REPLICATION-ROLE>
or better, when I should use it in a way different from 'origin'.
I've a logical replication setup and both master and client
connections default to 'origin', so it has to be specified manually.
What is its meaning?

Thanks,
Luca
