1568: Merge join selects do not filter left join
A join filter that evaluates to false or nil can still return rows in certain cases. One of the cases we evaluated incorrectly were LEFT_MERGE_JOINs with multiple filters, which should always return the left row even if a filter returns false. MERGE_JOIN's first filter is specially selected because its Left/Right expressions reference attributes for two tables that will arrive sorted given the indexes we chose to read. We use that first filter for the merge comparison direction.
1566: set utf8mb3_general_ci as information_schema database's collation
DataGrip expects utf8mb3_general_ci as information_schema's default collation for MySQL.
