# PostgreSQL

Source and Destination Databases

## Before you begin Before you begin, gather this connection information: * Name of the server that hosts the database you want to connect to * Database name * User name and password * Are you connecting to an SSL server? ## Connect and set up the workspace Launch Syntho and select **Connect to a database**, or **Create workspace**. Then select **PostgreSQL** from **Type** under **The connection details**. For a complete list of data connections, click **Type** under **The connection details**. Then do the following: 1. Enter the name of the server that hosts the database that you want to connect to. 2. Enter the database name to connect to the contained database. 3. Enter the port number. 4. Enter user name and password. Select the **Require SSL** check box when connecting to an SSL server. 5. Select **Next**.\ If Syntho can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact your network administrator or database administrator. ## Considerations & limitations * For JSON and XML columns, turn off validation in target and/or enable **ALTER** permission for user. * When entering database or schema names, use lowercase letters. Names containing capital letters must be entered in lowercase to ensure a proper connection. ### Supported data types This table outlines the support and limitations for various data types in PostgreSQL when using connectors. It indicates what's supported per generator type, and if any additional processing is performed by Syntho to successfully generate and write the data. | Data type | AI-powered generation | Mockers | Mask | Calculated columns | Other | | ------------------ | -------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | **SMALLINT** | [True](https://docs.syntho.ai/configure-a-data-generation-job/configure-column-settings/ai-powered-generation#discrete) | [True](https://docs.syntho.ai/configure-a-data-generation-job/configure-column-settings/mockers/numeric-integer) | [True](https://docs.syntho.ai/configure-a-data-generation-job/configure-column-settings/mask/numeric-integer) | [True](https://docs.syntho.ai/configure-a-data-generation-job/configure-column-settings/calculated-columns#suported-data-types) | -
