Locking in Inheritance partition

We have a declarative partition on tables in our database which is PG10. We face issues as the table becomes locked during attach and detach and cannot be used during the event.

We have a master and slave setup and application query points to Slave but whenever we perform attach and detach of partitions on Master the locks propagates to slave and causes Application to spin.

Kindly suggest if  Inheritance partition will help here or any other way I can avoid this lock.

Thanks,

Gaurav
