Next time it would be nice if the test case was self-contained. Wasn't that difficult to figure out the table layout, though. :)
Got it - will add next time.

As usual this will be done after a couple of days, if no problems appear. I'm pretty sure there won't but sticking to my workflow here.
Do you want patches for the back ports as well?
I noticed that between 9.6 (which is what we're using with this customer) and 10 the variable arrsiz was renamed to arrsize, so slight differences. Did not check earlier releases yet.
