WDR Snapshot Schema
After the WDR snapshot function is enabled (enable_wdr_snapshot is set to on), schema snapshot is created in user tablespace pg_default in database postgres to flush WDR snapshot data. By default, the initial user or the monadmin user can access the snapshot schema.
You can set the parameter wdr_snapshot_retention_days to automatically manage the snapshot lifecycle.
NOTICE
Do not add, delete, or modify tables in the snapshot schema. Manual modification or damage to these tables may cause WDR exceptions or even WDR unavailability.
