Add automatic type cast for integer literals

Browse source 
In parameterized statements integer literals, like Int(num), are replaced with a placeholders. For some expressions,
postgres interpreter will not have enough information to deduce the type. If this is the case postgres returns an error.
Int8, Int16, Int32.... functions now will add automatic type cast over a placeholder, so type deduction is always possible.
