-- Returns information about Amazon Redshift security groups. If the name
-- of a security group is specified, the response will contain only
-- information about only that security group.
--
-- For information about managing security groups, go to
-- <https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-security-groups.html Amazon Redshift Cluster Security Groups>
-- in the /Amazon Redshift Cluster Management Guide/.
--
-- If you specify both tag keys and tag values in the same request, Amazon
-- Redshift returns all security groups that match any combination of the
-- specified keys and values. For example, if you have @owner@ and
-- @environment@ for tag keys, and @admin@ and @test@ for tag values, all
-- security groups that have any combination of those values are returned.
--
-- If both tag keys and values are omitted from the request, security
-- groups are returned regardless of whether they have tag keys or values
-- associated with them.
--
-- This operation returns paginated results.
