3. Capture the rsa.db.dba.password information using the ./rsautil manage-secrets -a get com.rsa.db.dba.password command.  Enter the Operations Console admin name and password when prompted.
4. The database password is echoed back.
5. Connect to database with the ./psql command.
6. Paste the database password when prompted 

rsaadmin@am81p:~> cd /opt/rsa/am/utils
rsaadmin@am81p:/opt/rsa/am/utils> ./rsautil manage-secrets -a get com.rsa.db.dba.password
Please enter OC Administrator username: <enter the Operations Console admin's name>
Please enter OC Administrator password: <enter the Operations Console admin's password>
com.rsa.db.dba.password: <com.rsa.db.dba.password string>
rsaadmin@am81p:/opt/rsa/am/utils> cd ../pgsql/bin
rsaadmin@am81p:/opt/rsa/am/pgsql/bin> ./psql -h localhost -p 7050 -d db -U rsa_dba
Password for user rsa_dba: <enter the com.rsa.db.dba.password captured above>

7. In the command line, type the query shown here as one line:

SELECT relname 
AS "Table", pg_size_pretty(pg_total_relation_size(relid)) 
AS "Size", pg_size_pretty(pg_total_relation_size(relid) - pg_relation_size(relid)) 
AS "External Size" 
FROM pg_catalog.pg_statio_user_tables 
ORDER BY pg_total_relation_size(relid) DESC;

db=# SELECT relname AS "Table", pg_size_pretty(pg_total_relation_size(relid)) AS "Size", 
pg_size_pretty(pg_total_relation_size(relid) - pg_relation_size(relid)) as "External Size" 
FROM pg_catalog.pg_statio_user_tables ORDER BY pg_total_relation_size(relid) DESC;
                  Table                   |    Size    | External Size
