PostgreSQL PII Detection and Redaction

A PostgreSQL experiment identifies personal-information spans and applies role-dependent masking while keeping the surrounding message readable.

The implementation ideas below are our interpretation of the community demo. Check the original post for the author’s actual setup.

Where this fits

Let support tools show the context needed for a task while reducing exposure of names, addresses, and other personal details.

How to build on the idea

Detect candidate sensitive spans, validate their positions against the source text, then apply deterministic masking rules for the viewer’s role.

An illustrative decision

These examples explain a possible workflow; they are not recorded demo results or API request and response formats.

Example input
Message: Contact Alex at alex@example.com. Viewer role: guest.
Example decision
Identify the name and email spans; show a version with those spans masked under the guest policy.

Scope and limitations

Missed spans remain possible. Review how model inputs leave your environment before handling real personal data, and test redaction against your own document formats.

Try a decision of your own

Define the context and a small set of choices in the playground, then use the API guide to connect your application.
