EDB Postgres Advanced Server is stable from version to version. My company didn't have any issues stability-wise, so I'd give it an eight.

I rate EDB Postgres Advanced Server's stability an eight out of ten. 

This is an extremely robust, enterprise-grade solution that inherits all of the same reliability aspects of Ingress.

Postgres itself is very stable. I can't really say that anything about the stability of the producT is bad. It's our first choice to use after Oracle. If we can avoid to set up Oracle to reduce some costs, we use Postgres. It depends on the application side. I work in the IT department but the company is not an IT company. We approach solutions from a technological perspective. Most of the time we have to deal with the client, the market, the vendors and deploy their applications on different databases. So we look to use Postgres if it's possible. But if the vendor doesn't certify the application on Postgres we need to deploy on a database that is certified for the application and we cannot use it as a solution.

I think that the stability of the solution is very good. It is a very stable solution.  

The database has had stability issues.
