When will id be null in a primary key?
The OP seems to be aware of this...
"We cannot change the query being executed. Is there any way we can
make the query planner ignore `OR (id IS NULL)` (as that will never be
the case for the PK) and use both `id` clauses in the index condition?"

Yes, agreed.
But if the query is supposed to be generic and re-used in a situation
where id could be null, wouldn't the null id records be fetched every time?
