That doesn't really respond to the "means what?" question --- which of
"nextval" and "next_seq" is the early binding form, and how do you
remember?  For that matter, how do you even remember that they're
related?  Still, I have no strong objection to those names, and am happy
to go with them if that will resolve the discussion.

We already have the function to do late binding, namely nextval(text).
I see no percentage in inventing some random new name for a function
that's been there forever --- unless the new name adheres to some
standard, which these don't.
