Should there be a charcat?

Column |     Type      | Modifiers
--------+---------------+-----------c      | character(20) |

decibel=# select c, c || ('x'::char) from c;         c           | ?column?
----------------------+----------x                    | xx

I would think that c || 'x' would result in 'x                    x', but it doesn't because the only text
concatenationfunction we have is textcat(text,
 
text). As soon as you cast a char to text, you lose all the trailing spaces.

Is this what the spec says should happen?
