I'm inclined to think this was probably a good thing before 9.6, as a
guard against accidentally writing an empty query into a script and
thus executing more queries than you meant to. However, with the new
end-of-command definition I think it's impossible to write an empty
query without an explicit ";", so it seems fine now. Pushed.
