I am totally impressed by the work 2ndQuadrant is doing: many of the recent innovations to Postgres have been done by them and all of that without any obligation for them to be doing so. The BSD license would allow them to add all of these things to a proprietary fork that they could be selling.

Or they could just release their own fork under an open license and focus on just adding features.

But that's not how they work. All of their contributions are pushed upstream which is a very considerable effort with how conservative Postgres is at accepting new functionality.

Aside of that: there are 2ndQuadrant employees in the #postgres IRC chat room, helping people with daily support issues. This is their core business and yet they still help people for free (within reason). This is bloody impressive.

If I'm ever at a point when I need help with a Postgres issue, then they will be very first of the list of companies I would consider.

Thank you very much for all that you are doing.
