Let $Y$ be a regular, integral scheme of dimension $1$. Is it true that $Y$ is locally Noetherian?
To prove local Noetherianity it is enough to show that for any open affine $U=\mathrm{Spec}(A)\subseteq Y$, the ring $A$ is Noetherian. Then the answer to my question would be "yes" if we could prove the following:
Claim: let $A$ be an integral domain of Krull dimension $1$ such that for any nonzero prime ideal $\mathfrak{p}\lhd A$ the local ring $A_{\mathfrak{p}}$ is regular. Then $A$ is Noetherian.
Any help directed towards answering the first question and proving (or disproving) the claim would be greatly appreciated!
Note: I actually know that for a ring $R$, even if every local ring is regular of dimension 1, it could be that $R$ is not Noetherian. However, it seems to me that all the counterexamples to this claim that I know of start from a ring with zero divisors.
