Generated `Params` don't allow nullable values when `COALESCE` is used

Version

1.25.0

What happened?

I'm trying this

I expected the generated UpdateEnvParams to contain nullable types since:

the schema contains NOT NULL fields
the update SQL contains COALESCE(?, <fieldname>)

Since the field is constrained as NOT NULL in the schema, then this allows updating a field when ? is not null, and leaving the field alone if ? is null.

Ideally, the user would pass some null fields and some not-null fields and I could pass those through to sqlc transparently via the generated UpdateEnvParams that would contain nullable types to pass to the SQL.

Database schema

CREATE TABLE env (
    "id" INTEGER PRIMARY KEY,
    "name" TEXT NOT NULL,
    "comment" TEXT,
    "create_time" TEXT NOT NULL,
    "update_time" TEXT NOT NULL,
    UNIQUE(name)
) STRICT;

SQL queries

-- name: UpdateEnv :exec
UPDATE env SET
    name = COALESCE(?, name),
    comment = COALESCE(?, comment),
    create_time = COALESCE(?, create_time),
    update_time = COALESCE(?, update_time)
WHERE id = ?;
