I got a way to reproduce the same error pattern with the following
trick:
--- a/src/backend/utils/misc/injection_point.c
+++ b/src/backend/utils/misc/injection_point.c
@@ -357,6 +357,8 @@ InjectionPointDetach(const char *name)
int idx;
int max_inuse;
+ pg_usleep(5 * 1000000L);
+
LWLockAcquire(InjectionPointLock, LW_EXCLUSIVE);
Now looking at it, and for the reason why 010 for concurrent indexes
does not complain..
