Using PostgreSQL as Document Store

npm install llamaindex @llamaindex/postgres

You can configure the schemaName, tableName, namespace, and connectionString. If a connectionString is not provided, it will use the environment variables PGHOST, PGUSER, PGPASSWORD, PGDATABASE and PGPORT.

import { Document, VectorStoreIndex, storageContextFromDefaults } from "llamaindex";
import { PostgresDocumentStore } from "@llamaindex/postgres";
 
const storageContext = await storageContextFromDefaults({
  docStore: new PostgresDocumentStore(),
});
