Streaming Data into Postgres with Estuary

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.
