Have Postgres >this functionality? I'm missing how this is useful. Even having such a feature there is not any way to duplicate a test trace: execution time of a request is not guaranteed even if it's issue time is repeatable wrt some epoch. And if there are concurrent requests, their completion order is not guaranteed. It is also true in Oracle, and in every general purpose DBMS that I know of. So what exactly do you "test" using a fixed date/time?
