# PostgreSQL

UI Bakery allows you to easily connect to a PostgreSQL database with no need for additional layers like APIs or third-party services.

## Configuration

### Prerequisites

If your database is hosted behind a Firewall, you need to add our [IP addresses](/concepts/data-sources.md#whitelisting-ip-addresses) to the Firewall whitelist.

### Connecting the data source

1. On the **Data sources** page, click **Connect**, and select *PostgreSQL* in the Data sources list.
2. Specify all the required credentials.

{% hint style="warning" %}
If you're connecting via **bit.io**, make sure to specify your **repository name** in the *Schemas name* field. Click *Add* to save it, otherwise you'll get an error.

![](/files/b9tGebhewIHfGLoEUmW2)
{% endhint %}

3. Click **Test connection** to check whether the data source can be connected, and then click **Connect Datasource** to complete the setup.

UI Bakery will extract the database structure and store column types. This data will be used to suggest proper [table columns and form field types](/concepts/components/work-with-components/field-types-and-types-recognition.md).

If you need to be able to override the default data source database with a custom value in an action, you can enable the **Allow override database name in action** setting.

Once enabled, when configuring the action, you will be able to specify a custom database. In case a database is not specified, the default data source database will be used.

## Usage

Once you have established the connection between UI Bakery and PostgreSQL, you can access its data - load it and send it back.

The following *Action steps* are supported with PostgreSQL:

* [Load Table](/reference/working-with-actions/load-table-action.md)
* [Load Row](/reference/working-with-actions/load-row-action.md)
* [Create Row](/reference/working-with-actions/create-row-action.md)
* [Bulk Create Rows](/reference/working-with-actions/bulk-create-rows-action.md)
* [Update Row](/reference/working-with-actions/update-row-action.md)
* [Delete Row](/reference/working-with-actions/delete-row-action.md)
* [Bulk Delete Rows](/reference/working-with-actions/bulk-delete-rows-action.md)
* [SQL Query](/reference/working-with-actions/sql-query.md)
