It doesn't work the other way for DROP.  The error you get in the DROP
case is a low-level error that really should never be seen by users.
But I see that as a problem with DROP, not with RENAME.

In my view, once the code has determined which relation (identified by
OID) is meant, it should be OK to take the OID as identifying the
relation henceforth.  This is not significantly different from the fact
that

    create table a (...);
    create view v as select * from a;
    alter table a rename to b;

will leave view v referencing b.  Would you claim that v should break?
