## AI overview

PostgreSQL Anonymizer 3.2 adds faster localized pseudonymization functions, deprecates the previous pseudo_* functions, and fixes three critical privilege-escalation vulnerabilities.

## Source excerpt

Eymoutiers, France, Septembre 4th, 2026 Dalibo is pleased to announce PostgreSQL Anonymizer 3.2 introducing a new panel of fast pseudonymization filters. Enhanced Privacy Protection for Your Data PostgreSQL Anonymizer is an extension that hides or replaces personally identifiable information (PII) or commercially sensitive data from a PostgreSQL database. The extension offers 6 different masking strategies: Dynamic Masking - Real-time data protection Static Masking - Permanent data transformation Replica Masking - Anonymized logical replication Backup Masking - Privacy-protected database exports Masking Views - Controlled data visibility Masking Data Wrappers - Extended protection across systems Each strategy is complemented by an enhanced suite of Masking Functions, including advanced techniques such as: Substitution, Randomization, Faking, Pseudonymization, Partial Scrambling, Shuffling, Noise Addition and Generalization. The extension can be installed with Debian and RPM packages, an Ansible role, a Docker image, etc. You can use it on most major DBaaS providers including : Alibaba Cloud, Crunchy Bridge, Google Cloud SQL, IBM Cloud, Microsoft Azure Database, Neon, Yandex It is also available on some Postgres forks such as EDB Advanced Postgres, Greenplum and Yugabyte. See the INSTALL section of the documentation for more details! Fast and Localized pseudonymization Although Pseudonymization is not Anonymization, it may be useful in some contexts. Until version 3.1, this was achieved with a panel of pseudo_* functions, such as anon.pseudo_last_name(...), anon.pseudo_email(...), etc. These functions are now replaced by a new panel of anon.seeded_* functions, such as anon.seeded_last_name(...), anon.seeded_email(...), etc. The anon.seeded_* functions have 2 main advantages over the previous ones: They can be localized, e.g anon.seeded_street_name(id,'fr_FR') They are 40x faster :) The anon.pseudo_* functions are kept for backward compatibility but are now deprecated
