DDL code uses tuple descriptors to pass around pg_attribute values during table and index creation. But tuple descriptors don't include the variable-length/nullable columns of pg_attribute, so they have to be handled separately. Right now, the attoptions field is handled in a one-off way with a separate argument passed to InsertPgAttributeTuples(). The other affected fields of pg_attribute are right now not needed at relation creation time. The goal of this patch is to generalize this to allow handling additional variable-length/nullable columns of pg_attribute in a similar manner. For that, create a new struct FormExtraData_pg_attribute, which is to be passed around in parallel to the tuple descriptor and optionally supplies the additional columns. Right now, this struct only contains one field for attoptions, so no functionality is actually changed by this.
