k8s环境出现，pod锁定的情况，老的pod不解除锁定，新的pod就无法加入

By running the following command:

select * from DATABASECHANGELOGLOCK;

You should be able to check the lockedby column to see who locked the table. Generally, the lock will be from the local machine.

Assuming this is the case (and no other machine has a lock on the database), this should resolve the issue:

Execute the following SQL query against the database:

update DATABASECHANGELOGLOCK
set locked=0, lockgranted=null, lockedby=null
where id=1
