I think Tom's point is whether octet_length() should regard input text
being encoded in the client side encoding or not.
My vote is octet_length() assumes database encodeding.
If you need client side encoded text length, you could do something
like:
select octet_length(convert('foo',pg_client_encoding()));
Note that there was a nasty bug in convert() which prevents above
working. I have committed fixes.
