Problem
Evaluate PostgreSQL native logical replication as a baseline for Hosted Memory 2 synchronization and validate its behavior under normal and failure conditions.
Part of #2442
Solution
Added a PostgreSQL sync test using a local PostgreSQL instance and cloud RDS PostgreSQL. Tested native logical replication, including initial sync, continuous changes, network outages, PostgreSQL restarts, and recovery/catch-up after reconnection.
Also evaluated the limitations around offline operation, WAL retention, blobs, analytics/observability, and multi-robot/peer-to-peer access.
How to Test
Run the PostgreSQL sync test and verify changes replicate between the local and cloud PostgreSQL databases.
AI assistance
ChatGPT (GPT-5.6 Luna) — assisted with PostgreSQL replication commands, and documentation. All implementation and commands were reviewed and understood manually.
