I want to use logical replication for implementing multimaster (so all nodes 
are both sending and receiving changes).
But there is one "stupid" problem: how to prevent infinite recursion and not to 
rereplicate replicated data.
I.e. node receives change set from some other node, applies it within some 
transaction, it is  written to the log and ... is replicated to other nodes.
In my experiments with receiver_raw/decoder_raw infinite recursion actually 
doesn't happen because unique constraint violation.
But it is neither nice, neither efficient way of stopping infinite recursion.

I wonder if there is some better way to prevent some particular transaction 
from been replicated?

Thanks in advance,
