Check Details

In PostgreSQL data sync scenarios, the sync task will check whether the replication parameter wal_level is set to logical. At the same time, the sum of the number of selected databases for sync and the value of replication_slots must be smaller than or equal to the value of max_wal_senders.

Troubleshooting

Set the value of wal_level to logical.
Reduce the number of databases to be synced.
