Sure, the "DROP SERIAL" I proposed would rather "change" the data type to int by dropping the default and would delete referring pg_depend entries. Read it more as a kind of "drop autoincrement functionality for this column". The problem I see (but you might see it differently) is that you can't drop this autoincrement stuff without also dropping the column once you forbid to change the default (yeah I know, changing the default is even worse and leaves you with incorrect dependencies).
