Noah Misch 5882ca6686 Call xlc __isync() after, not before, associated compare-and-swap. ... Architecture reference material specifies this order, and s_lock.h inline assembly agrees. The former order failed to provide mutual exclusion to lwlock.c and perhaps to other clients. The two xlc buildfarm members, hornet and mandrill, have failed sixteen times with duplicate key errors involving pg_class_oid_index or pg_type_oid_index. Back-patch to 9.5, where commit b64d92f1a5 introduced atomics. Reviewed by Andres Freund and Tom Lane.		2016-02-19 22:47:50 -05:00
