AFAIK, the coercion does occur when needed but it gives a clear error
message when appropriate. I mean simple situations like
CREATE TABLE test ( i4 INT4, i8 INT8 );
insert into test ( i8 ) select 99999999999999999;
update test set i4 = i8;
ERROR: integer out of range
Could you perhaps give an example of your problem?
