Connect GX Cloud to PostgreSQL

Prerequisites​

Optional. Create a separate PostgreSQL user​

  1. In pgAdmin, select a database.

  2. Click Tools > Query Tool.

  3. Paste the following code into the Query pane to create and assign the gx_role role and allow GX Cloud to access all public schemas and tables on a specific database.

    pgAdmin
     -- Create and assign the gx_role role and allow GX Cloud 
     -- to access all public schemas and tables on a specific database
     CREATE ROLE gx_role WITH LOGIN PASSWORD '<your_password>';
     GRANT CONNECT ON DATABASE <your_database> TO gx_role;
     GRANT USAGE ON SCHEMA public TO gx_role;
     GRANT SELECT ON ALL TABLES in SCHEMA public TO gx_role;
     ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO gx_role
    • Replace <your_password> and <your_database> with your own values.
    • ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO gx_role; is optional and gives the gx_role user access to all future tables in the defined schema.

  4. Click Execute/Refresh.

Connect to a PostgreSQL Data Source and add a Data Asset​

  1. In GX Cloud, click Data Assets > New Data Asset > New Data Source > PostgreSQL.

  2. Enter a meaningful name for the Data Source in the Data Source name field.

  3. Enter a connection string in the Connection string field. The connection string format is:

    PostgreSQL connection string
    postgresql+psycopg2://YourUserName:YourPassword@YourHostName:5432/YourDatabaseName

    If you created a separate PostgreSQL user for your GX Cloud connection as recommended above, use those credentials in the connection string.

  4. Click Connect.

  5. Select one or more tables to import as Data Assets.

  6. Click Add x Asset(s).

  7. Decide which common data quality issues you want to start monitoring. By default, GX Cloud adds Expectations to detect Schema, Volume, and Completeness issues. You can de-select recommendations you’d like to opt out of.

  8. Click Start monitoring or Finish.
