That looks like strace output from pgbench, and I don't see any
interesting differences between v10 and v11 (though I'm surprised to
see it using poll() instead of ppoll(), and opening a new connection
for every transaction).
How about syscalls on the server side? You could start it with
something like "strace -f path/to/postgres -D path/to/pgdata" (-f for
follow children), and perhaps also use -c so that it shows aggregated
data (up until you ^C it) instead of every syscall?
