Function GetStaticallyKnownType

postgres/parser/sem/tree/type_name.go:188–191

GetStaticallyKnownType possibly promotes a ResolvableTypeReference into a *types.T if the reference is a statically known type. It is only safe to access the returned type if ok is true.

(ref ResolvableTypeReference)

// *types.T if the reference is a statically known type. It is only safe to
// access the returned type if ok is true.
func GetStaticallyKnownType(ref ResolvableTypeReference) (typ *types.T, ok bool) {
	typ, ok = ref.(*types.T)
	return typ, ok
}

// MustBeStaticallyKnownType does the same thing as GetStaticallyKnownType but panics
// in the case that the reference is not statically known. This function
