We started using it for BDR, but unfortunately too much software
explodes spectacularly when you use it, due to simplistic/buggy
version parsing.

This led me to push for wider adoption of server_version_num - in
particular, exposing it as an initial connection parameter via
GUC_REPORT, and exposing it in pg_config. After a few attempts I've
given up on that as a lost cause now, though I still disagree with the
rationale.

Right now, if you use it, various 3rd party software will fail in a
variety of exciting ways, some more subtle than others.
