postgres-config update --config max_slot_wal_keep_size=2GB. ... max_replication_slots: Defines the number of replication slots for data streaming.
PostgreSQL 13: Don't let slots kill your primary
If max_slot_wal_keep_size is zero, which is the default value, then there’s no limit. I don’t recommend this, because it leads to failures when slots fill the disk.
Amazon Aurora PostgreSQL parameters
The max_slot_wal_keep_size parameter controls the quantity of WAL data that the RDS for PostgreSQL DB instance retains in the pg_wal directory to serve slots.
