We settled on a near-zero-downtime migration from PostgreSQL 13 to 16 using **pglogical**:

- Configure the existing pg13 primary as publisher and the new pg16 cluster as subscriber.
- Let replication catch up, then cut over during the **Sunday 02:00 maintenance window**.
- Avoided pg_dump/restore because downtime was a priority.

The publisher/subscriber setup was already configured and syncing in @session:default/20260810_091500_aa11bb.

We settled on a **near-zero-downtime logical-replication migration** rather than dump/restore:

- Upgrade the analytics cluster from **Postgres 13 to Postgres 16**
- Use **pglogical**: the existing pg13 primary as publisher, a new pg16 node as subscriber
- Let replication catch up, then perform cutover in the **Sunday 02:00 maintenance window**

The publisher/subscriber sync had already been configured. See @session:default/20260810_091500_aa11bb.

We chose a near-zero-downtime migration to PostgreSQL 16 using **pglogical**:

- Configure the existing PostgreSQL 13 primary as the publisher.
- Bring up the new PostgreSQL 16 instance as a subscriber and let it sync.
- Perform the final cutover during the **Sunday 02:00 maintenance window**.

This was set up in @session:default/20260810_091500_aa11bb.
