Hi there,

Actual discussion is here: https://github.com/pgjdbc/pgjdbc/issues/3482
In brief: I do understand that "select 1 as one, 2 as two, 3 as three" might
have lack of type info. But I suppose, in case these values are used in the
assignment, the type could be taken from the corresponding column type. Like
for "insert into sometable(one, two, three) select 1 as one, 2 as two, 3 as
three" it is obvious that types should match.
