   If the collation is not important to the function execution we can create a 
separate pattern for it where we will exclude parameters that do not need 
casting. For example, substring is done in that way. We only cast if it is 
DefaultST or ExplicitST to ImplicitST, as we need the return type to have 
implicit collation.
