pg-cdc is an open source tool that streams Postgres Write Ahead Logs (WAL) into typed, immutable Apache Iceberg tables on AWS S3. It registers entities in the AWS Glue Catalog and gates all reads via AWS Lake Formation tags, enabling AI agents, analysts, and query engines to consume governed data without database credentials or a JVM. Key properties include one-way data flow (no write-back risk), IAM-based authentication, column-level access control, and built-in time travel via Iceberg snapshots.
