Yeah, I've noticed this as well (although it doesn't appear to be
documented). Would we gain anything by enforcing this restriction? IMHO
not a lot...

We specifically do not require a semicolon at the very end of the
function definition.  My recollection is that the plpgsql grammar did
originally enforce that, and we relaxed it because it confused people.
You have to admit that
    ... END;';
is a bit odd-looking.

Yeah, makes sense. Attached is a doc patch. Barring any objections I'll
apply it to HEAD by end-of-day today.

Improved wording that doesn't telegraph, "Look at me!":

    Each declaration and each statement within a block is terminated by a
    semicolon, though the final <literal>END</literal> that concludes a
    function does not require one.
