-- As of 8.3 we have removed most implicit casts to text, so that for example
-- this no longer works:

select length(42);

-- But as a special exception for usability's sake, we still allow implicit
-- casting to text in concatenations, so long as the other input is text or
-- an unknown literal.  So these work:

select 'four: '::text || 2+2;
select 'four: ' || 2+2;

-- but not this:

select 3 || 4.0;
