ERROR: cannot convert relation containing dropped columns to view

Hello

I get this error message :
ERROR:  cannot convert relation containing dropped columns to view

I have googled, but find only very old posts that doesn't seem to be the
same situation.

What I have done is that I have a quite big table that I added a column
to for deletion time.

Then I droped that column and added it again with the right type.

After that I cannot create a rule that is returning data.

The reason I have to return data is irrelevant here, but PostgREST
expects that.

To reproduce:
create table foo
(
id serial,
deleted int
);

alter table foo drop column deleted;
alter table foo add column deleted timestamp;

CREATE or replace RULE del_post AS ON DELETE TO foo
DO INSTEAD
update foo set deleted = now()
WHERE id = OLD.id
returning *;

returns:
ERROR:  cannot convert relation containing dropped columns to view


If I don't drop any column (adding the right type at once) it works as
expected.

two questions:
1) is this a bug
2) is there a way to "cean" the table from the deleted columns without
recreating it?

Best Regards
