PostgreSQL | Lade

Lade officially supports deploying PostgreSQL databases.

Supported Versions

The following PostgreSQL versions are supported and receive security updates:

Provisioning PostgreSQL

A PostgreSQL addon can be provisioned with the CLI:

$ lade addons create postgres --name mydb

You will be prompted to select an available plan, region, and version.

Attaching to Your App

Your PostgreSQL addon can be attached to your app with the CLI:

$ lade addons attach mydb --app myapp

When your addon is attached, the DATABASE_URL and POSTGRES_URL environment variables will be added to your app.

You can confirm these environment variables were added to your app with the lade env list command.

Accessing Your Database

To access your database remotely, you will need to enable public access on your addon. You can view settings with the lade addons show command. The addon URI will follow the format:

postgresql://<user>:<password>@<host>:<port>/<dbname>

You can access your remote database with the psql command:

$ psql <addon URI>
psql (17, server 17)
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

user=#

PostgreSQL Extensions

You can enable required PostgreSQL extensions with the CREATE EXTENSION command:

$ psql <addon URI>
psql (17, server 17)
Type "help" for help.

user=# CREATE EXTENSION citext;
CREATE EXTENSION
user=# CREATE EXTENSION hstore;
CREATE EXTENSION
