Checked Postgres 17 and DuckDB 1.5.6. DuckDB refuses to mix 2D and 1D lists
(binder error), so it doesn't help here. Postgres skips a NULL argument:
`array_cat(ARRAY[[NULL,NULL,60]], NULL::int[])` is `{{NULL,NULL,60}}` and NULL
+ NULL is NULL. The fix gives exactly that, so I'll follow Postgres and open a
PR.
