History question: Why does select round(3,3) work, select round(3.0,3) work, but select round(3.0::real,1) not work?
There's a utility cast in the integer case (described here http://www.postgresql.org/docs/9.3/static/typeconv-func.html), but not in the real case. Is this on purpose, or just an oversight? Obviously one can work around it, but I'm sick of doing so, it makes my SQL examples ugly. I’d like to fix it, but not if there’s a reason it’s not supposed to be done.
