-- List the tables in a database. If neither @SchemaPattern@ nor
-- @TablePattern@ are specified, then all tables in the database are
-- returned. A token is returned to page through the table list. Depending
-- on the authorization method, use one of the following combinations of
-- request parameters:
--
-- -   Secrets Manager - when connecting to a cluster, specify the Amazon
--     Resource Name (ARN) of the secret, the database name, and the
--     cluster identifier that matches the cluster in the secret. When
--     connecting to a serverless workgroup, specify the Amazon Resource
--     Name (ARN) of the secret and the database name.
--
-- -   Temporary credentials - when connecting to a cluster, specify the
--     cluster identifier, the database name, and the database user name.
--     Also, permission to call the @redshift:GetClusterCredentials@
--     operation is required. When connecting to a serverless workgroup,
--     specify the workgroup name and database name. Also, permission to
--     call the @redshift-serverless:GetCredentials@ operation is required.
--
-- For more information about the Amazon Redshift Data API and CLI usage
-- examples, see
-- <https://docs.aws.amazon.com/redshift/latest/mgmt/data-api.html Using the Amazon Redshift Data API>
-- in the /Amazon Redshift Management Guide/.
--
-- This operation returns paginated results.
