Libelle DataMasking vs PostgreSQL Anonymizer

Libelle DataMasking has no write-up on Specifiction yet; its figures are above.

PostgreSQL Anonymizer is an extension for masking or replacing personally identifiable and commercially sensitive data in PostgreSQL databases. Masking rules can be written in SQL with PostgreSQL DDL and kept in the database schema. Its documented approaches include anonymous dumps, static and dynamic masking, replica masking, masking views, and data wrappers. Functions can randomize, fake, partially scramble, shuffle, add noise, generalize, or apply custom transformations. A masked role can export anonymized data through pg_dump; masking rules should then be removed from the dump. Identifier detection searches common names in English and French, but may flag non-identifiers or miss identifiers. Installation instructions cover Linux and self-hosted PostgreSQL. The extension can be built from source on macOS, without community support there; Windows use is described through PostgreSQL on WSL2, as there is no native build. Installation requires superuser privileges, so a cloud database provider must offer the extension in its catalog. The plan is free. Commercial support is available separately.
