Hence sharing. > > https://pgdash.io/blog/postgres-12-generated-columns.html Interesting, indeed. Version 12 has been released today with many other features. I am mostly interested in the performance improvements of CTEs: https://paquier.xyz/postgresql-2/postgres-12-with-materialize/ -- Christian Barthel <bch@online.de>

There are lots of performance improvements in 12. He had a backup/archiving script that runs at the end of month. He reported saving of 10 hours for about 3-4TB of data. This was without changing the script. CTEs is also a widely used concept. This will really help many. -- Pankaj Jangid
