Hi,
designing things upon fresh master I found that varnullingrels contains
numbers that is out of the outer joins index range.
Anywhere in documentation I see that this field contains outer join
relids. But after the 247dea8 it simply isn't true.
So, I propose at least to change comments (see attachment). Since the
doc was out of scope, I wonder if someone analysed the impact of this
change on the whole optimiser logic.
