How We Built Postgres Compatibility in Rust: pgwire and DataFusion
Summary
GreptimeDB describes building PostgreSQL compatibility using pgwire and the DataFusion ecosystem to enable a top-down Postgres like ecosystem. It covers the Postgres protocol layers, the benefits of protocol compatibility, and how pgwire and datafusion-postgres enable pg_catalog support for broader tool and driver compatibility. The article also highlights reusable libraries and mentions related open-source projects working toward a Postgres like ecosystem.
