I remembered Bucardo does multi-master replication. Tried to look on the
internet how to set it up, but apparently, my RDS PG 12 is already
considered a "master". So I think there is no reason for me to disable the
triggers on the target_db. Again, I do not remember where I read this.

Waiting for someone to confirm this...
