I just realised that the failure of the specific mentioned test case was unrelated to the issue at hand, as it correctly shows that you can't use int8-opclasses for int4 columns. The attached fixes that test case by creating a table with a bigint column instead, so that the test correctly, but unexpectedly, outputs "ERROR: unexpected non-btree AM: NNNNN". - Matthias
