There are two Asserts in nodeMergejoin.c that are reachable if the input data is not in the expected order. This seems way too fragile. Alexander Lakhin reported a case where the assertions could be triggered with misconfigured foreign-table partitions, and bitter experience with unstable operating system collation definitions suggests another easy route to hitting them. Neither Assert is in a place where we can't afford one more test-and-branch, so replace 'em with plain test-and-elog logic. Per bug #17395. While the reported symptom is relatively recent, collation changes could happen anytime, so back-patch to all supported branches.
