Can we add Assert(!is_internal) to the ProcedureRelationId case in
sepgsql_object_access() too?  I don't see any caller that would set it
true anywhere, but maybe you have a good reason for omitting it.

I'm not clear on what's sepgsql_relation_setattr for; it doesn't seem to
be called anywhere (other than sepgsql_relation_setattr_extra, but
that's static, so why isn't sepgsql_relation_setattr also static?).  But
I notice that it calls sepgsql_index_modify without first checking for
the toast namespace like the other callers do.  Is this okay or an
oversight?

I admit the new RELKIND_INDEX cases in various places make for strange
flow.  Not sure how it can be improved though.

I didn't find anything wrong with the changes to src/backend.  One thing
that I noticed is that when bootstrapping, all relation creation is
considered internal.  I am sure this is okay fo the normal case, but I
wonder if a malicious superuser could get a hold of things that he
shouldn't by starting a bootstrapping backend and run relation creation
there.

Note: I can compile sepgsql but not run the regression tests.
