Hi!
I have planned replacing sequences with UUIDs, which work in distributed networks.

Hi Experts,
I am reaching out to seek your guidance and expertise on handling sequences in a bi-directional logical replication setup.
I am planning to set up two PostgreSQL-16 database servers with logical bi-directional replication, using the `origin=none` configuration. In this setup, my application will be connecting to either of the database servers for DML operations.
Given this scenario, I am looking for the best practices to handle sequence values to ensure consistency and avoid conflicts. Specifically, I would like to understand:
1. How to configure sequences to avoid duplicate values in both database servers.
2. Whether there are specific settings or configurations in PostgreSQL that facilitate the management of sequences in a bi-directional replication environment.
3. Any recommendations or strategies to ensure smooth and consistent sequence management across the two servers.
I appreciate any guidance you can provide on this matter.
Thank you!
