# pgx-geos

[![PkgGoDev](https://pkg.go.dev/badge/github.com/twpayne/pgx-geos)](https://pkg.go.dev/github.com/twpayne/pgx-geos)

Package pgx-geos provides [PostGIS](https://postgis.net/) and

[GEOS](https://libgeos.org/) support for

[`github.com/jackc/pgx/v5`](https://pkg.go.dev/github.com/jackc/pgx/v5) via

[`github.com/twpayne/go-geos`](https://pkg.go.dev/github.com/twpayne/go-geos).

## Usage

### Single connection

```go

import (

    // ...

    "github.com/jackc/pgx/v5"

    "github.com/twpayne/go-geos"

    pgxgeos "github.com/twpayne/pgx-geos"

)

// ...

    connectionStr := os.Getenv("DATABASE_URL")

    conn, err := pgx.Connect(context.Background(), connectionStr)

    if err != nil {

        return err

    }

    if err := pgxgeos.Register(ctx, conn, geos.NewContext()); err != nil {

        return err

    }

```

### Connection pool

```go

import (

    // ...

    "github.com/jackc/pgx/v5/pgxpool"

)

// ...

    config, err := pgxpool.ParseConfig(connectionStr)

    if err != nil {

        return err

    }

    config.AfterConnect = func(ctx context.Context, conn *pgx.Conn) error {

        if err := pgxgeos.Register(ctx, conn, geos.NewContext()); err != nil {

            return err

        }

        return nil

    }

    pool, err := pgxpool.NewWithConfig(context.Background(), config)

    if err != nil {

        return err

    }

```
