We now have horizontal sum, any all. coalesce was added, too.
Inner and left inequality joins should work well on all backends (via a workaround in polars). Full inequality joins do not work on all backends if the join condition is too fancy (not mergeable or hashable, to quote postgres). But these kinds of operations can always be done via two left joins.
MSSQL does now behave like the other backends on string comparisons, but accomplishing this requires extra work (length comparisons and collations).
