Yeah, that's unsurprising. You can also get some discrepancies from the
expected output if you, eg, run with nondefault planner parameters.
Thanks for pointing this out though, because I notice that somebody
stuck a bunch of plain EXPLAIN commands into rowsecurity.sql, in clear
violation of the project policy about using COSTS OFF in regression
explain commands. That's causing some though not all of your diffs,
and might lead to pseudo-failures in other environments that we do
consider supported. I'll go fix that ...
