PSQL wire protocol 🔌

A pure Go PostgreSQL server wire protocol implementation. Build your own PostgreSQL server within a few lines of code. This project attempts to make it as straight forward as possible to set-up and configure your own PSQL server. Feel free to check out the examples directory for various ways on how to configure/set-up your own server.

🚧 This project does not include a PSQL parser. Please check out other projects such as auxten/postgresql-parser to parse PSQL SQL queries.

package main

import (
	"context"
	"fmt"

	wire "github.com/jeroenrinzema/psql-wire"
)

func main() {
	wire.ListenAndServe("127.0.0.1:5432", handler)
}

func handler(ctx context.Context, query string) (wire.PreparedStatements, error) {
	return wire.Prepared(wire.NewStatement(func(ctx context.Context, writer wire.DataWriter, parameters []wire.Parameter) error {
		fmt.Println(query)
		return writer.Complete("OK")
	})), nil
}
