# PostgreSQL

Connect to a PostgreSQL database.

## Connection details

| Field             | What to enter                    |
| ----------------- | -------------------------------- |
| **Host**          | The database server's address    |
| **Port**          | The port the database listens on |
| **Database name** | The database to connect to       |
| **Username**      | The user to connect as           |
| **Password**      | That user's password             |

The password is never shown again after you save it.

## Tips

* Create a **read-only user** for Zerve if your notebooks only need to read data.
* If the database only accepts approved IP addresses, allow Zerve's outbound IP. See [Connecting to databases with IP allowlists](/zerve-docs/data-and-assets/connections.md#connecting-to-databases-with-ip-allowlists).

See [Data connections](/zerve-docs/data-and-assets/connections.md) for creating, naming and attaching connections.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.zerve.ai/zerve-docs/data-and-assets/connections/postgresql.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
