How do I tell sqlc to omit a field in the json if it's empty

[adityaladwa]

Let's say I have a table

create table "todos" (
    "id" uuid primary key default uuid_generate_v4(),
    "title" varchar(255) not null,
    "description" text default null
);

After I run sqlc generate the following model will be generated:

type Todo struct {
	ID          uuid.UUID `json:"id"`
	Title       string    `json:"title"`
	Description sql.NullString    `json:"description"`
}

I would like to omit the description if it's empty (as it's a nullable column).

Now, I can use column override and use string type instead of sql.NullString. So now the generated type will be

type Todo struct {
	ID          uuid.UUID `json:"id"`
	Title       string    `json:"title"`
	Description string   `json:"description"`
}

The problem with this is that if Description is nil, it won't be omitted from the json response. So the response would be something like this:

{
    "id": "c0507d40-de51-451f-b84e-c2f06af7710f",
    "title": "This is a todo",
    "description": null
}

Is there a way I can tell sqlc to add omitempty tag to a particular field? (Description field in this case)

Any other way to solve this issue?
