Why Partial<typeof x.$inferInsert> is required for Partial Updates

export const timestamps = {
  createdAt: timestamp('created_at').notNull().defaultNow(),
  updatedAt: timestamp('updated_at').notNull().defaultNow(),
};

export const modifiers = {
  createdBy: varchar('created_by', { length: 64 }).notNull(),
  updatedBy: varchar('updated_by', { length: 64 }).notNull(),
};

export const organizations = pgTable('organizations', {
  organizationId: varchar('organization_id', { length: 64 }).primaryKey(),
  name: varchar('name', { length: 255 }).notNull(),
  deleted: boolean('deleted').notNull().default(false),
  expired: boolean('expired').notNull().default(false),
  expirationDate: timestamp('expiration_date').notNull(),
  plan: varchar('plan', { length: 64 }).notNull(),
  ...modifiers,
  ...timestamps,
});

await db.update(organizations)
  .set({
    name,
    updatedBy: uid,
    updatedAt: new Date(),
  })
  .where(eq(organizations.organizationId, organizationId));

await db.update(organizations)
