i thought there was unistall sql file -

----- googleanalytics-UNINSTALL.sql ------
-----------------------------------------------
SET @t4=0;
SELECT (@t4:=configuration_group_id) as t4
FROM configuration_group
WHERE configuration_group_title= 'Google Analytics Configuration';
DELETE FROM configuration WHERE configuration_group_id = @t4 AND configuration_group_id != 0;
DELETE FROM configuration_group WHERE configuration_group_id = @t4 AND configuration_group_id != 0;
DROP TABLE IF EXISTS google_analytics_languages;
------

hope this helps.
