Sorry for the CI breakage!

The Assert(ndims >= 2) in multi_sort_init() failed for join stats that
have a single filter column. Attached v2 that fixed it (relaxed to
ndims >= 1, plus a shadowed variable warning from GCC).      

The pg_upgrade failure is expected due to the new catalog columns.
I will post a fix soon.

Best,
Alex
