Great to see such a project. We are using datanymizer [1] right now but it has gone unmaintained and we are using my patched version [2] and it is working pretty well for us. I saw a new project that is getting close in terms of having the feature set I need and has them on their roadmap [3].

To ensure that we are marking columns as PII, we run a job that compares the anonymization configuration to a comment on the column- we have a comment on every column to mark it as PII (or not).

Other tools I found that do some anonymization but didn't meet my needs:

  * https://github.com/DivanteLtd/anonymizer
  * https://postgresql-anonymizer.readthedocs.io/en/stable
  * https://nitzano.github.io/dbzar/
