That doesn't really sound like an actual problem to me. If the error
is that the constraint is inherited, that suggests that the solution
is to find the place from which it got inherited and drop it there.
And that's in fact what you have to do. What's the problem? I mean,
we could add a hint, but it's possible to make yourself sound dumb by
giving hints that are basically obvious implications from the error
message. Nobody wants this sort of thing:

rhaas=# drop table foo;
ERROR: table "foo" does not exist
HINT: Try dropping a table with a different name that does exist, or
first create this table before trying to drop it.

A hint here wouldn't be as silly as that, but I think it is
unnecessary. I doubt there's likely to be much confusion here.
