Re: [I] Postgresql driver does not support multidimensional arrays [arrow-adbc]

lidavidm commented on issue #3621:

   I think we explicitly punted on this at the time given that Arrow didn't have any real type for this. IIRC, Postgres multidimensional arrays can have a different set of dimensions in every row, right? Now that we have [fixed_size_tensor](https://arrow.apache.org/docs/format/CanonicalExtensions.html#variable-shape-tensor), we could try mapping to this type.
