Do not allow removal of superuser privileges from bootstrap user.
A bootstrap user who is not a superuser will still own many
important system objects, such as the pg_catalog schema, that
will likely allow that user to regain superuser status. Therefore,
allowing the superuser property to be removed from the superuser
creates a false perception of security where none exists.
Although removing superuser from the bootstrap user is also a bad idea
and should be considered unsupported in all released versions, no
back-patch, as this is a behavior change.
