toast_save_datum() ended with two copies of the same three steps, one each external on-disk TOAST pointer: allocate a datum, set its tag, then copy the contents from a varatt_external_oid or a varatt_external_oid8 into it. These steps are moved into a new helper function, toast_pointer_build(), which takes the tag and a pointer to the struct and derives everything else from the tag. For now, only two varatt_external_* exist for external on-disk TOAST pointers. Some more are under discussion, where this refactoring shows some benefits in the shape of less duplication. There should be no behavior change. Author: Nikhil Kumar Veldanda <veldanda.nikhilkumar17@gmail.com> Discussion: https://postgr.es/m/CAFAfj_FeJQZrKyVn7ur0aJx8iz8SR14NheVJNyc8JNoqtMX+og@mail.gmail.com
