Check Detail

PostgreSQL sync scenario will check whether the copy parameter wal_level is equal to logical, and at the same time, replication_slots need to meet the number of databases for sync + replication_slots <= max_wal_senders.

Set the instance parameter wal_level to logical.
Reduce the number of databases to be synchronized.
