This test looks similar to me but I cannot say what is the difference. My tests are done under heavier load maybe. Also I couldn't reproduce this with a table with low num number of columns (integrer and text). I am not sure if this is relevant...

Uhm, that's very...interesting. I'll look closely next week. Though I didn't have a chance to reproduce yet. We have fixed similar problem in 14.1. And now we have very similar TAP test to you reproduction [0]. How do you think, what's the key difference between TAP test and your repro?
