how to restrict dba to access sensitive data

[Patrizio Bassi <patrizio.bassi@xxxxxxxxx>]

Hi All,

i took a look into docs but could not find if pgsql has anything similar to Oracle Database Vault ( for instance cfr. 

https://www.oracle.com/technetwork/database/options/database-vault/overview/ds-security-dv-12cr2-3493647.pdf ) to restrict high privileged accounts from accessing tables with sensitive data. Encryption is not an option unfortunately.

Thank you

Patrizio
