The cast to cidr isn't implicit anymore anyway. What I currently have
it marked as is "assignment". You could make the argument that it
should be marked "explicit only" to avoid silent loss of data. But
we have the numeric downcasts marked as "assignment" so I don't see
why this case is different. If you do
insert into int4_tbl values(7.7);
what's inserted into the integer column is 8, and I've not heard anyone
complaining that that represents unacceptable data loss.
