Connect to TDSQL PostgreSQL

Connection Steps

Please follow the steps below to connect to the TDSQL PostgreSQL data source.

1. Click "New Data Connection" in the upper right corner of the data connection page.

2. Select the TDSQL PostgreSQL data source from the data source types.

3. Fill in the required parameters for the data source connection as prompted.

   Connection Configuration Information Description

   Field	Description
   Name	The name of the connection. Required and unique within the user.
   Host Address	The address of the database. If the URL field is filled in, the URL will take precedence.
   Port	The port of the database. If the URL field is filled in, the URL will take precedence.
   Username	The username for the database.
   Password	The password for the database.
   Database	The name of the database.
   Schema	The schema of the database.
   Max Connections	The maximum number of connections in the connection pool.
   Encoding	The encoding setting for the database connection.
   ssl	Whether to use SSL connection.
   Prefer using database comment as dataset title	Whether to display the table name or the table comment as the title. When enabled, the title is shown; when disabled, the table comment is shown.
   sslmode	Fill in according to PostgreSQL configuration, such as "disable", "allow", "prefer", "require", "verify-ca", "verify-full".
   URL	The JDBC URL of the database.
   Hierarchical loading of schema and tables	Disabled by default. When enabled, schemas and tables are loaded hierarchically. Only schemas are loaded during connection; you need to click the schema to load the tables under it.
   Query Timeout (seconds)	Default is 600. When the data volume is large, you can appropriately increase the timeout.
   Allow Write Operations	Indicates that this connection can be selected as an output connection in Data Integration and Batch Sync. You must have write permissions to the database and pass verification before configuring this parameter.
   Support uploading files to specified path	Indicates the database name where the table generated when creating a local file dataset is stored. You must have write permissions to the database and pass verification before configuring this parameter.
   Only show tables under specified database/schema	When this option is selected and the database field is not empty, only tables under the specified db are displayed.

4. After filling in the parameters, click the Validate button to get the validation result (this checks the connectivity between HENGSHI SENSE and the configured data connection; you cannot add the connection if validation fails).

5. After validation passes, Allow Write Operations and Support uploading files to specified path will be enabled (previously disabled). You can choose whether to enable these two options.

6. Click Execute Preset Code to pop up the preset code corresponding to this data source, then click the execute button.

7. Click the Add button to add the TDSQL PostgreSQL connection.

Please note

1. Parameters marked with * are required; other parameters are optional.
2. When connecting to a data source, you must execute the preset code. Failure to do so may result in certain functions being unavailable during data analysis. In addition, when upgrading from a version prior to 4.4 to 4.4, you need to execute the preset code for existing data connections in the system.
