Bug Fixes

Fixed the following issues:

• When a user queries data from an external table in an external catalog, access to this table is denied even when the user has the SELECT privilege on this table. SHOW GRANTS also shows that the user has this privilege. #44061
• str_to_map may cause BEs to crash. #43930
• When a Routine Load job is going on, running show proc '/routine_loads' is stuck due to deadlock. #44249
• Persistent Index of Primary Key tables may cause BEs to crash due to issues in concurrency control. #43720
• The pending_task_run_count displayed on the page of leaderFE_IP:8030 is incorrect. The displayed number is the sum of Pending and Running tasks, not Pending tasks. In addition, the information of the metric refresh_pending cannot be displayed using followerFE_IP:8030. #43052
• Some SQL queries that contain CTEs may encounter the Invalid plan: PhysicalTopNOperator error. #44185
