Estuary now provides native support for real-time data streaming into PostgreSQL via its PostgreSQL materialization connector. With this, users can configure Flow collections to automatically write into PostgreSQL tables — in seconds, at scale, and with exactly-once semantics.

Whether you’re using a self-hosted Postgres instance or a managed database like Amazon RDS, Google Cloud SQL, or Azure Database for PostgreSQL, Estuary ensures secure and reliable connectivity — including support for SSL and SSH tunneling.

Key Features:

• Automatically creates target tables for each collection
• Supports standard and delta updates
• Handles schema evolution and reserved Postgres keywords
• Preserves column capitalization and converts data types (e.g., ipv4, macaddr, duration)
• Open-source compatible with Docker image:
  ghcr.io/estuary/materialize-postgres:dev

This connector is part of Estuary Flow — a real-time data platform that bridges Postgres with upstream systems like Kafka, MongoDB, APIs, and more.
