All those direct uses of object_access_hook make me think that the
InvokeObjectAccessHook() macro we have is insufficient.  Maybe we could
have InvokeObjectAccessHookArg1() so that instead of

+   if (object_access_hook)
+   {
+       ObjectAccessPostCreate  pc_arg;
+
+       memset(&pc_arg, 0, sizeof(ObjectAccessPostCreate));
+       pc_arg.is_internal = is_internal;
+       (*object_access_hook)(OAT_POST_CREATE, AttrDefaultRelationId,
+                             RelationGetRelid(rel), attnum, (void *)&pc_arg);
+   }

we can have
InvokeObjectAccessHookWithArgs1(OAT_POST_CREATE, AttrDefaultRelationId,                RelationGetRelid(rel), attnum,
            ObjectAccessPostCreate, is_internal, is_internal) 

which would expand into the above.  (Since ObjectAccessPostCreate has
two members, we presumably need InvokeObjectAccessHookWithArgs2 as
well.  But that doesn't seem to be used anywhere, so maybe that struct
member is not necessary?)

The second hunk to alter.c does not apply anymore; please rebase.
