Hi Tom (and others) Thank you for input. I think my next steps will be approcching the problem from differenct angles: Implement on Linux as Proof of Concept. Dive into the source for pgaudit and try to understand how it works, perhaps getting a small example extension working along the way. Perhaps contacting the authors of pgaudit to have them confirm that there exists working implementations of pgaudit on Windows (and if so if they are on PostgreSQL 11). I will report how this turns out.

Hm. I don't know much about pgaudit, but just from scanning its documentation, it doesn't seem like there's anything else that has to be set. I wonder whether pgaudit actually works on Windows? It might have some weird dependency on children being spawned with fork not exec, for instance. You probably ought to contact the authors and ask. regards, tom lane
