PgColumnBuilderBase and notNull()

holy mother of types ... could someone help me out here?

export function ref(id: AnyPgColumn): PgColumnBuilderBase {
  return bigint({ mode: 'number' })
    .references((): AnyPgColumn => id)
}

export function ref(id: AnyPgColumn): PgColumnBuilderBase {
  return bigint({ mode: 'number' })
    .references((): AnyPgColumn => id)
}

export function ref(id: AnyPgColumn): PgColumnBuilderBase {
  return bigint({ mode: 'number' })
    .references((): AnyPgColumn => id)
}

export function ref(id: AnyPgColumn): PgColumnBuilderBase {
  return bigint({ mode: 'number' })
    .references((): AnyPgColumn => id)
}

OK:

id: ref(sometable.id)

id: ref(sometable.id)

id: ref(sometable.id)

id: ref(sometable.id)
KO:

id: ref(sometable.id).notNull()

id: ref(sometable.id).notNull()

id: ref(sometable.id).notNull()

id: ref(sometable.id).notNull()

Is there a base type or interface I can use that does include

notNull()

notNull()

notNull()

notNull() and friends?
