Upgrading PostgreSQL is definitely on our To Do list, but there are a few bumps in the road. The first is that a glibc upgrade causes big problems for sort in PostgreSQL, which we have to work around first. We have changed our replication very recently as a first step towards getting to a newer PostgreSQL. As for exactly when that will happen, I’m not totally certain, but it is actively being worked on.
As you can imagine, we have to be very careful with this as it’s fine and dandy for us to manage our own PostgreSQL, but to introduce a breaking change into On-Prem Sentry would be bad for everyone. Once we get it sorted for our own installations, we’ll get On-Prem Sentry sorted as well.
