Don't check status of logical replication slots

Browse Source 
We only want to check the status of physical replication slots
to determine whether a streaming replication standby has become
detached and there is therefore a risk of uncontrolled WAL buildup
on the local node.

It's not feasible to second-guess the state of logical replication
slots.
