I've played a little time with this and this looks good to me ,
including 5-min pgbench runs with backtrace_functions set (it behaves
stable even for pgbench -C which stresses it much). Cfbot is also
green.
One thing i've I think I've noticed (but I've double-checked that's
not related to backtrace_functions set) - so it's that apparently
backends on windows leak(?) a tiny bit of memory - it's like 5
backends leak like 5 * <1kB / second @ ~3k TPS total as seen by
Resource Manager, yet i have no time to investigate that), anyway it's
does not seem to be connected to $topic.
Maybe one outstanding question is the answer to Michael's earlier question.
