Documentation

Overview

Package awspostgres provides connections to AWS RDS PostgreSQL instances.

URLs

For postgres.Open, awspostgres registers for the scheme "awspostgres". The default URL opener will create a connection using the default credentials from the environment, as described in https://docs.aws.amazon.com/sdk-for-go/api/aws/session/. To customize the URL opener, or for more details on the URL format, see URLOpener.

See https://gocloud.dev/concepts/urls/ for background information.

Example
package main

import (
	"context"
	"log"

	"gocloud.dev/postgres"
	_ "gocloud.dev/postgres/awspostgres"
)

func main() {
	// PRAGMA: This example is used on gocloud.dev; PRAGMA comments adjust how it is shown and can be ignored.
	// PRAGMA: On gocloud.dev, add a blank import: _ "gocloud.dev/postgres/awspostgres"
	// PRAGMA: On gocloud.dev, hide lines until the next blank line.
	ctx := context.Background()

	// Replace these with your actual settings.
	db, err := postgres.Open(ctx,
		"awspostgres://myrole:swordfish@example01.xyzzy.us-west-1.rds.amazonaws.com/testdb")
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()

	// Use database in your program.
	db.ExecContext(ctx, "CREATE TABLE foo (bar INT);")
}
