Adding Peter and Heikki here.
That may look like a corruption, but by re-running the tests this is
reproducible, right? Are you running a simple "make check"? Perhaps
you forgot to clean up your source directory before recompiling? Or
is that an installcheck on an existing instance, which has some
particular configuration not checked in the buildfarm? This query
uses only BTEqualStrategyNumber here. Now, it seems to me that this
could point to an actual bug, where the consistent function tries to
use a picksplit, but it should not in a certain code path. I am not
really a gist expert, just saying, but there are diffs between 13 and
14 in this area.
