Ants and Andres suggested to replace the spinlock used in pgss_store() with
LWLock. I agreed with them and posted the POC patch doing that. But I think
the patch is an item for v14. The patch may address the reported performance
issue, but may cause other performance issues in other workloads. We would
need to measure how the patch affects the performance in various workloads.
It seems too late to do that at this stage of v13. Thought?
I agree that it's too late for v13.
Thanks for the comment!
So I pushed the patch and changed default of track_planning to off.
