-- PERFORMANCE SCHEMA INSTALLATION
-- Note that this script is also reused by mysql_upgrade,

-- existing database named &#039;performance_schema&#039; if it
-- can contain user data.
-- In case of downgrade, it&#039;s ok to drop unknown tables
-- from a future version, as long as they belong to the
-- performance schema engine.
