Right. It's the same underlying routines; it would actually be pretty
hard to make the above cast behave differently from input into a column
of INTERVAL MONTH type, or from the interval-literal case. In all these
cases we are taking a string and cramming it into the input conversion
function for the INTERVAL datatype. The conversion function has access
to the typmod (ie the encoded <interval qualifier>) but it doesn't know
much more about the context than that.
