-E shows the queries internally generated by psql. The fact that these
change from version to version should not surprise you.
In this particular case, psql now has another mechanism to find out
whether you are superuser, and so it doesn't need to issue a query.
(This was part of a general effort to reduce connection startup
overhead.)
