Ask HN: What are the open source tools for database subsetting?

I have a very huge Postgres database that I need to clone locally (like 0.01 if its data) and do some tests. I have tried to use Jailer [0] (complicated to use. Like after installing it with the dpkg command, how do we launch it?) or Condenser [1] (intuitive but producing errors). Is there any other open source program to produce a small subset of the data available in a PostgreSQL? Like I like the fact that in Condenser you only tell the config file that you want 1% of the initial data and it does.
