No logical replication. Are we sure this only impacts logical and not physical? Thanks for the pointer - interesting one. We do use physical replication. Replicas were shut down and they closed their connections to this writer instance around 04:25 just before pg_ctl stop was executed on the writer itself. Something was on the writer DB's CPU before shutdown; metrics show total CPU for that linux namespace (k8s pod) around 0.86 cores until 04:24 and then the CPU starts dropping when the database shuts down. Bu 04:28 the CPU is under 0.01 cores and the CPU remains effectively zero until the processes are SIGKILL'd 30 minutes later. -Jeremy -- To know the thoughts and deeds that have marked man's progress is to feel the great heart throbs of humanity through the centuries; and if one does not feel in these pulsations a heavenward striving, one must indeed be deaf to the harmonies of life.
