Document a few caveats in synchronous logical replication.
In a synchronous logical setup, locking [user] catalog tables can cause

catalog tables to access them so exclusively locking those in transactions
can lead to deadlock. To avoid this users must refrain from having
exclusive locks on catalog tables.
