# Adapters

Altertable exposes standard SQL endpoints so existing clients and pipelines can query the lakehouse without custom SDKs.

- [Postgres](/docs/query-data/adapters/postgres.md): Connect to Altertable with the Postgres wire protocol so SQL clients and BI tools can query governed lakehouse data.
- [Arrow Flight SQL](/docs/query-data/adapters/arrow-flight-sql.md): High-performance streaming analytics with Arrow Flight SQL. Built on Apache Arrow, ideal for dbt, Airbyte, and large datasets.
