This release had quite a few patches that just weren't quite ready to go out yet, so were not included. There was some work done which reduces the per-connection overhead and allows many many more direct PG connections before performance degrades, while increasing overall performance with high connection counts by a ton...but it just wasn't quite ready and missed the deadline by a little. The memory based stats collector is another patch in the same vein, where it wasn't quite ready for 13. That said, many of these features are quite impressive and will offer nice wins for many workloads, incremental sorting is very cool, as is the memory bound hash aggregation. I'm with you on automatically updated materialized views, it's been something i've needed and been waiting for a long while now, and I am hoping it gets more focus. The current patch-set being worked on for it seems to have quite a few limitations.
