Ask HN: Do you use Percona Distribution of PostgreSQL? How's it working for you?

I am curious how the "free" Percona Distribution for PostgreSQL compares to the official community PostgreSQL distribution.

1. How long have you been using the Percona Distribution for PostgreSQL?

2. Do you use it in production? If not - why not?

3. What are the features you find valuable

4. Are there somethings to be aware of
