You can find information about the operations supported by the Postgres node on the [integrations](https://n8n.io/integrations/n8n-nodes-base.postgres) page. You can also browse the source code of the node on [GitHub](https://github.com/n8n-io/n8n/tree/master/packages/nodes-base/nodes/Postgres).

## Prerequisites

Create an user account on a Postgres server. 

## Using Database Connection

2. Use the credentials and connection parameters with your Postgres node credentials in n8n.
