ArrayCoerceExpr

ArrayCoerceExpr represents a type coercion from one array type to another, which is implemented by applying the perelement coercion expression "elemexpr" to each element of the source array. Within elemexpr, the source element is represented by a CaseTestExpr node. Note that even if elemexpr is a noop (that is, just CaseTestExpr + RelabelType), the coercion still requires some effort: we have to fix the element type OID stored in the array header.
