Master baker tier. Every paragraph earns its place on the tray.
Summary
pg_lake is a PostgreSQL extension developed by Snowflake Labs that enables Postgres to function as a lakehouse system by integrating with Iceberg tables and data lake files. The extension allows users to create and modify Iceberg tables directly from PostgreSQL with full transactional guarantees, query and import data files from object storage in formats like Parquet, CSV, JSON, and Iceberg, and export query results back to object storage. This transforms PostgreSQL into a standalone lakehouse platform that can work with both transactional data and raw data files in cloud storage.
