Lightup account setup

Lightup needs a user account that can query data and metadata for all tables you want to monitor. You might already have a user set up that will work, or you might need to create one. Grant the user sufficient privileges using security roles.

Postgres 14

You can run the following DDL to create a user account named lightup and grant it privileges; just substitute a password for <strong_password_here>:

CREATE USER lightup WITH LOGIN BYPASSRLS ENCRYPTED PASSWORD '<strong_password_here>' IN ROLE pg_read_all_data;

Postgres 11-13

Run the following DDL to set up a role and the lightup user account, with the following adjustments:

• You can use whatever role name you want (readaccess is just an example).
• GRANT CONNECT on all databases you want Lightup to see (cdb is just an example).
• GRANT USAGE ON and GRANT SELECT ON ALL TABLES IN SCHEMA for all schemas you want Lightup to see (testdata is just an example).
• Substitute your own password for **redacted**.

CREATE ROLE readaccess;
GRANT CONNECT ON DATABASE cdb TO readaccess;
GRANT USAGE ON SCHEMA testdata TO readaccess;
GRANT SELECT ON ALL TABLES IN SCHEMA testdata TO readaccess;
CREATE USER lightup WITH LOGIN BYPASSRLS ENCRYPTED PASSWORD '**redacted**';
GRANT ROLE readaccess TO lightup;

Connector setting

• Host Name - The hostname for the datasource (check the browser address bar; you want the string between // and /). Example: https://host.na.me/
• Database Name - The name of the database you're connecting to.
• Username - Enter lightup.
• Password - The username account's password.

Schema scan frequency

You can adjust how often scans run for a datasource.

• In section 3 - Advanced, select a value for Schema scan frequency: Hourly, Daily, or Weekly.

Query governance

Postgres datasources support the Query history, Scheduling, Enable data storage, and Maximum backfill duration settings. For steps, see Set query governance settings for a datasource.
