Hi, RKN!
Transaction isolation level can be set at the beginning of each individual transaction.
You can read more about transaction isolation level at [0].
There are many settings which can be configured different on Standby. E.g. default_transaction_isolation [1]. This is
expectedbehaviour, AFAIK.
Thanks!
