Works for me:
regression=# delete from p_kto where kto_id = 101;
ERROR: update or delete on "p_kto" violates foreign key constraint "c_dkt_kto_id" on "depot"
DETAIL: Key (kto_id)=(101) is still referenced from table "depot".
I think you've not told us the full truth about your tables. The quoted
definitions are syntactically wrong (missing commas) and semantically
wrong (kto_id has no UNIQUE or PRIMARY KEY constraint, therefore can't
be the target of a foreign key reference). I think you stripped out
everything you thought was irrelevant, including the actual source of
the problem --- maybe there is another constraint that is ON DELETE
CASCADE, and it happens to get processed first?
