IIUC, the objects here we are talking about are removed because of
their dependency type AUTO at least the existing case of 'drop table'.
So, I think the current behavior suggested by Nisha sounds correct and
consistent with the pre-existing 'drop table' case. Also, we display
such case at DEBUG2 level, see following code in dependency.c:

if (extra->flags & (DEPFLAG_AUTO |
DEPFLAG_INTERNAL |
DEPFLAG_PARTITION |
DEPFLAG_EXTENSION))
{
/*
* auto-cascades are reported at DEBUG2, not msglevel.  We don't
* try to combine them with the regular message because the
* results are too confusing when client_min_messages and
* log_min_messages are different.
*/
ereport(DEBUG2,
(errmsg_internal("drop auto-cascades to %s",

We can consider displaying such a message for schema cases, if not
already there.
