Session Storage Adapter for PostgreSQL

This package implements the SessionStorage interface that works with an instance of PostgreSQL. Tested using PostgreSQL v15

import {shopifyApp} from '@shopify/shopify-app-express';
import {PostgreSQLSessionStorage} from '@shopify/shopify-app-session-storage-postgresql';

const shopify = shopifyApp({
  sessionStorage: new PostgreSQLSessionStorage(
    'postgres://username:password@host/database',
  ),
  // ...
});

// OR

const shopify = shopifyApp({
  sessionStorage: PostgreSQLSessionStorage.withCredentials(
    'host.com',
    'thedatabase',
    'username',
    'password',
  ),
  // ...
});

If you prefer to use your own implementation of a session storage mechanism that is compatible with the @shopify/shopify-app-express package, see the implementing session storage guide.
