That works only if the string lacks NULs and its length fits into int, 
and one must also convert the idx_t length to int (e.g., via a cast 
which I find tricky). Although these limitations could be documented, it 
might also be good to have an API like quotearg to generate a quoted or 
quotable string that can be printed with plain %s.
