PostgreSQL CDC Setup Tutorial: Real-Time Data Capture with Estuary (Step-by-Step)
Learn how to set up PostgreSQL Change Data Capture (CDC) with Estuary in under 10 minutes. This tutorial walks through enabling logical replication on Google Cloud SQL, creating the replication user, and connecting your Postgres database to Estuary for real-time streaming to Snowflake, BigQuery, Databricks, and more.
⚠️ Heads up: This video was recorded on an earlier version of Estuary. The core concepts (logical replication, replication user, Cloud SQL flags) still apply, but the UI and a few setup steps have been updated since. For the latest instructions, follow the docs: https://docs.estuary.dev/reference/Connectors/capture-connectors/PostgreSQL/

WHY POSTGRESQL CDC WITH ESTUARY
━━━━━━━━━━━━━━━━━━━━━━━
Estuary is a real-time data platform built for Change Data Capture. Unlike batch ETL tools, Estuary streams row-level changes from PostgreSQL's write-ahead log (WAL) to destinations like Snowflake, BigQuery, Databricks, Redshift, and ClickHouse with sub-second latency.
Works with PostgreSQL on:
- Google Cloud SQL
- Amazon RDS / Aurora
- Azure Database for PostgreSQL
- Supabase, Neon, Heroku
- Self-hosted PostgreSQL

PostgreSQL CDC: What, Why, and How
Set up PostgreSQL change data capture (CDC) without worrying about your WAL or replication slot loss. This step-by-step Postgres CDC guide covers WAL configuration, replication user setup, publication creation, and building your first real-time pipeline to Snowflake, Iceberg, or ClickHouse, no Kafka or Debezium required. We walk through why CDC beats batch replication for Postgres, how the WAL and replication slots actually work (and what goes wrong), and a full setup demo with Estuary, a real-time CDC platform that manages WAL advancement and decouples your source from your destination.

What is Postgres CDC? CDC, or change data capture, is a method to record all updates made to a database. In conjunction with PostgreSQL, CDC often uses the Postgres write-ahead log for data replication. We start discussing Postgres CDC at 3:36 2. When should you use CDC? Is it just for real-time data? CDC can be beneficial for many different use cases since it has a low impact on the replicated Postgres database and handles replication more efficiently than batch queries. Since CDC is also very low latency, it’s a top choice for real-time use cases, though batch workflows will still benefit from an efficiency/low-impact standpoint. We go over CDC use cases at 2:29 3. Is CDC complicated to implement? CDC can be complex when creating and managing a DIY solution. You need to be careful that the WAL doesn’t grow beyond expected bounds. A managed solution can make setup and maintenance much simpler; just make sure that the integration platform follows CDC best practices, like keeping the source and destination decoupled. A brief implementation guide with Estuary starts at 5:55 Media resources used in this video are from Canva and the YouTube Studio Audio Library.
