Oops I made a mistake.
Reference name is needed not an object name,
i.e
object relid
object oid
relerence relid
reference oid
reference name

create table a (...);
create view view_a as select .. from a;

Then we have an pg_depend entry e.g.

pg_class_relid
oid of the view_a
pg_class_relid
oid of the table a
'a' the name of the table

and so on.

drop table a; (unadorned drop).

Then the above entry would be changed to

pg_class_relid(unchanged)
oid of the view_s(unchagned)
pg_class_relid(unchanged)
InvalidOid
'a' the name of the table(unchanged)

create table a (...);

Then the pg_depend entry would be

pg_class_relid(unchanged)
oid of the view_s(unchagned)
pg_class_relid(unchanged)
the oid of the new table a
'a' the name of the table(unchanged)
