I have added mention of the new SQL standard part SQL/MDA
(multi-dimensional arrays) to the documentation.
This is not the same thing as the existing support for multidimensional
arrays in PostgreSQL. SQL/MDA targets huge arrays, aggregation over
slices, export as images, for applications in fields such as physics and
astronomy -- as I understand it. Something to look into perhaps at some
point, if there is interest, but right now it's just a mention that it's
not supported.
