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.
