Hi Sergei,
as far as I understand these restrictions apply when hot_standby is set to
on AND a recovery.conf is missing.
I can confirm that hot_standby is commented out - is this setting on by
default?
grep hot_standby /etc/postgresql/10/main/postgresql.conf
#hot_standby = on # "off" disallows queries during
recovery
#hot_standby_feedback = off # send info from standby to prevent
Cheers
