Changing cluster parameters does not take effect. (问题)更改集群参数后不生效

[rayn316]

Use "pg edit-config pg-meta" to manually change, or use the following command to change. Only "max_parallel_workers_per_gather" takes effect, while "max_connections" and "max_locks_per_transaction" do not take effect even when set to smaller values.

May I ask whether this lack of effectiveness in the modification is a bug, or is it necessary to restart the pg database? If a database restart is required, what would be the command? Currently, the changes only take effect by restarting the server.

使用 pg edit-config pg-meta 手动更改，或者使用下面命令更改，只有max_parallel_workers_per_gather生效，max_connections和max_locks_per_transaction不生效，设置为更小值也不生效

请问一下，这种改动不生效，是bug还是只能重启pg数据库才行，如果要重启数据库，命令是怎么样的，现在只能通过重启服务器生效

# 设置集群参数
pg edit-config -p max_connections=5000 --force pg-meta
pg edit-config -p max_locks_per_transaction=2000 --force pg-meta
pg edit-config -p max_parallel_workers_per_gather=16 --force pg-meta
