+### Setup: Create test tables with ListView arrays
+
+statement ok
+CREATE TABLE list_view_agg_test AS
+SELECT
+    id,
+    group_col,
+    arrow_cast(make_array(val1, val2, val3), 'ListView(Int64)') as list_view_col,

+    (2, 'A', 40, 50, 60),
+    (3, 'B', 70, 80, 90),

+    (5, 'C', 1, 2, 3)
+) AS t(id, group_col, val1, val2, val3);
+
+### Test: GROUP BY on ListView column
+
+query ?I rowsort
+SELECT list_view_col, COUNT(*)
