WDR Snapshot Schema

After the WDR snapshot function is enabled (the GUC parameter enable_wdr_snapshot is set to on), objects are created in the snapshot schema in the postgres database of the pg_default tablespace to persist WDR snapshot data. By default, the initial user or monitor administrator can access and operate objects in the snapshot schema.

You can set the GUC parameter wdr_snapshot_retention_days to automatically manage the snapshot lifecycle.
