Documentation

Overview

Package gcppostgres provides connections to managed PostgreSQL Cloud SQL instances. See https://cloud.google.com/sql/docs/postgres/ for more information.

URLs

For postgres.Open, gcppostgres registers for the scheme "gcppostgres". The default URL opener will create a connection using the default credentials from the environment, as described in https://cloud.google.com/docs/authentication/production. 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/gcppostgres"
)

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/gcppostgres"
	// PRAGMA: On gocloud.dev, hide lines until the next blank line.
	ctx := context.Background()

	// Replace this with your actual settings.
	db, err := postgres.Open(ctx,
		"gcppostgres://user:password@example-project/region/my-instance01/testdb")
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()

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