MDEV-18100: User defined aggregate functions not working correctly when the schema is changed
The issue here was that when the schema was changed the value for the THD::server_status
is ored with SERVER_SESSION_STATE_CHANGED.
For custom aggregate functions, currently we check if the server_status is equal to
SERVER_STATUS_LAST_ROW_SENT then we should terminate the execution of the custom
aggregate function as there are no more rows to fetch.
So the check should be that if the server status has the bit set for
SERVER_STATUS_LAST_ROW_SENT then we should terminate the execution of the
custom aggregate function.
