pgwire

This library implements PostgreSQL Wire Protocol, and provide essential APIs to write PostgreSQL comptible servers and clients.

This library is a work in progress.

Usage

Server

To use pgwire in your server application, you will need to implement two key components: startup processor and query processor. For query processing, there are two kinds of queries: simple and extended. In simple mode, the sql command is passed to postgresql server as a string. In extended query mode, a sql command follows parse-bind-describe(optional)-execute lifecycle.

Examples are provided to demo the very basic usage of pgwire on server side:

• examples/sqlite.rs: uses an in-memory sqlite database at its core and serves it with postgresql protocol.
• examples/gluesql.rs: uses an in-memory gluesql at its core and serves it with postgresql protocol.
• examples/server.rs: demos a server that always returns fixed results.
• examples/secure_server.rs: demos a server with ssl support and always returns fixed results.
