Is there some reason the question is specific to postgres13 , or did you just
say that because it's your development target for your project.
I think it almost certainly depends more on your project than on postgres 13.
It may well be that performance is better under btrfs, maybe due to compression
or COW. But you'd have to test what you're doing to find out - and maybe write
up the results.
Also, it's very possible that btfs performs better for (say) report queries,
but worse for data loading. Maybe you care more about reporting, but that's
not true for everyone.
