Security and Operational Best Practices for SQLite-PostgreSQL Sync Extensions (LiteSQL PostgreSQL)

An SQLite extension that syncs with PostgreSQL via logical replication is turning heads. The project behind it, LiteSQL PostgreSQL, shows how cross-database syncing can live inside everyday apps. ^[1]

Overview The idea is to extend SQLite with a module that taps PostgreSQL's logical replication to keep row data aligned across systems. The work lives on the LiteSQL PostgreSQL repository, illustrating a concrete path from local storage to a centralized data plane. ^[1]

Security considerations • Secure replication channels - Replication traffic should be protected to prevent sniffing or tampering across the network. ^[1] • Access controls - Limit which apps and users can subscribe to or publish replicated data. ^[1] • Credential management - Store and rotate credentials used by the extension to minimize breach risk. ^[1]

Tooling integration & patterns LiteSQL PostgreSQL on GitHub shows how tooling integration can align with security and operability in SQLite-to-PostgreSQL sync flows. Operators can study its approach for configuring connections, monitoring status, and handling failures. ^[1]

Closing thought Security-minded deployment is doable, and the repo serves as a practical reference for how SQLite and PostgreSQL can co-exist securely in production.
