The only possible explanation for this behavior is that somebody is signalling the postmaster due to Xid wraparound issues. This is keyed on some GUC vars -- Perhaps you have autovacuum_freeze_max_age set to an insane value?
Doesn't appear to be insane ?
#autovacuum_freeze_max_age = 200000000 # maximum XID age before forced vacuum
