Doh, of course -- I misread.

ReorderBufferCheckMemoryLimit is new in pg13 (cec2edfa7859) so now at
least we have a reason why this workload regresses in pg13 compared to
earlier releases.

Looking at the code, it does seem that increasing the memory limit as
Amit suggests might solve the issue.  Is that a practical workaround?
