session_replication_role

Is there a distinction between "ORIGIN" and "LOCAL" as related to
session_replication_role, and if so, what is it? I am unable to understand
from the documentation any distinction between the two settings.

The intent is that a system that is the "origin" for replication
changes (e.g. - a database where you'll be collecting
INSERT/UPDATE/DELETE information to replicate elsewhere) would run in
the "origin" role, normally.

The distinction from a practical perspective will take place when
stored functions that implement "replication stuff" detect what role
the system is in, and may behave differently.

Thanks for the reply. I was unable to detect any change in trigger operation
when setting the variable to origin or local. I understand that you are
saying that the distinction only exists if my code is written to operate
differently based on the setting.

Thanks for the input...
