Log Message:
-----------
Improve consistency of the error messages generated when you try to use
ALTER TABLE on a composite type or ALTER TYPE on a table's rowtype.
We already rejected these cases, but the error messages were a bit
random and didn't always provide a HINT to use the other command type.
