@alamb in parser we operate with expressions which works with arrow types. I understand the necessity of having arrow_typeof which seems to be a synonym for PG `pg_typeof` function. But for the potential `arrow_cast` function, we will return Expression as well with Arrow datatype inside, how it differs from usual cast? Perhaps you have the analogue in PG?
