Dear Jean-Paul Thank you very much for this link which is actually very interesting. I am going to study it carefully. But my problem is more generic: How to set up the encryption of sensitive data and have good performance (using an index by example) ?. Apparently it is not obvious as that.

This is ruled by the Payment Card Industry Data Security Standard (aka PCI DSS). I attend some years ago a real good presentation from Denish Patel, a well known community member. I saw this talk in pgconf 2015 in Moscow: https://pgconf.ru/media2015c/patel.pdf I recommend you read it, if you had not already? It shows code examples, etc. My 2 cents... -- Jean-Paul Argudo Ce message et toutes les pièces jointes (ci-après le 'Message') sont établis à l'intention exclusive des destinataires et les informations qui y figurent sont strictement confidentielles.
