Hello.
I defined a new type to represent an unsigned int, but when I try do run a
query it complains because it is not quoted and casted to my type.
Suppose I have a table:
-- my_uint32 is my new type
CREATE TABLE test (a my_uin32);
If I try to run this insert, postgres complain about the type:
INSERT INTO teste (a) VALUES (10);
But this one works:
NSERT INTO teste (a) VALUES ('10'::my_uint);
Is there a way to avoid the single quotes?

A constant like 10 is initially assigned one of the integer types (the
exact rules are in the documentation). In order to be able to store
that into a column of a custom type, you need to define a cast between
the integer type and your type with at least assignment context.
