Why unsigned integer is not available in PostgreSQL?
...pret strings as literals, just write '4294966272'::uint4 as your literals. Casts shouldn't be a huge deal either. You don't even need to do range exceptions, you can just treat the semantics of '4294966273'::uint4::int as -1024. Or you can throw an error.

Why is there no multiple inheritance in Java, but implementing multiple interfaces is allowed?

@curiousguy: If a framework provides that casting an object reference to a base-type reference will be identity preserving, then every object instance must have exactly one implementation of any base-class method. If ToyotaCar and HybridCar both derived from Car and...
Is it safe to use -1 to set all bits to true?
...
@litb: casting -1 is certainly a nice way to get maximal unsigned values, but it's not really descriptive; that's the reason why the _MAX constants exist (SIZE_MAX was added in C99); granted, the C++ version numeric_limits<size_t...

Why does int i = 1024 * 1024 * 1024 * 1024 compile without error?

Postgres manually alter sequence
...But if you feed typed variables to the function you may need explicit type casts to satisfy function type resolution. Like:
SELECT setval(my_text_variable::regclass, my_other_variable::bigint, FALSE);

Why doesn't Java offer operator overloading?
...and one double. There is even the whole pointer arithmetic domain (without casting, you can add to a pointer an integer, but you cannot add two pointers...).
In Java, there is no pointer arithmetic, but someone still found string concatenation without the + operator would be ridiculous enough to ju...
