Well, there are two different length() functions --- length(text)
and length(bytea) are entirely different things, they don't even
measure in the same units. I think documenting them separately
is the right thing to do. I don't really have a problem with
repeating the entries for other functions that exist in both
text and bytea variants, either. There aren't that many.

Meh. Seems like what that would mostly do is ensure that
neither page is understandable on its own.
