+1. In early XC days, we focused a lot on adding newer features and
supporting as many PG features as possible. That took its toll on the
testing and QA. It was a mistake though my feeling was we tried to correct
that to some extend with XL. We did a 9.5 merge, which of course was a big
deal, but other than more time is being spent on improving stability and
performance

XL was very easy to break and I'm wondering how many corner cases still

Your team reported 2 or 3 major issues which I think we were able to fix
quite quickly. But if there are more such issues which your team has
recorded somewhere, I would request you to send them to the XL mailing
list. I would definitely want to look at them and address them.

Thanks,
