Hi all,
In pgql-general, I reported that the queue order changed in the following cases. [1] ・Multiple sessions request row locks for the same tuple ・Update occurs for target tuple I would like to hear the opinion of experts on whether it is a specification or a bug. I think row locking is a FIFO specification, using tuple header and lock managers. Therefore, I think that the above is a bug.
