I'd read https://www.postgresql.org/docs/current/dynamic-trace.html#DEFINING-TRACE-POINTS and then go see if those tracepoints are fully conforming to the coding rules in the modified version. A plausible bet is that their entries in probes.d don't entirely match up with the calls in the source code. You could compare the relevant bits of code between vanilla and modified 16.4 if the problem isn't immediately obvious. regards, tom lane
