Backing up/restoring Postgres database in vCO 5.1 appliance is similar to backup/restore of VCSA as described in the above KB article, with the following differences:
- database location -> /var/lib/pgsql/data
EMB_DB_INSTANCE,EMB_DB_USER, EMB_DB_PASSWORD -> take a look at file /opt/vmo/appliance/dbd/create_db.sql
Hope this helps,
