Please look at the following query, which triggers an error after ae4569161:
SET random_page_cost = 1;
CREATE TABLE tbl(u UUID);
CREATE INDEX idx ON tbl USING HASH (u);
SELECT COUNT(*) FROM tbl WHERE u = '00000000000000000000000000000000' OR
   u = '11111111111111111111111111111111';

ERROR:  XX000: ScalarArrayOpExpr index qual found where not allowed
LOCATION:  ExecIndexBuildScanKeys, nodeIndexscan.c:1625

Best regards,
Alexander
