I could see a true column store having much better performance than
tricking a row base

At the high level, it's about avoiding fetching data you don't need.
In a row store system, in general you must fetc

An interesting topic we have also discussed in our team.
Realistically - this is more about picking the right software for the job.
PostgreSQL has come so far up in it's performance for more general workloads
that it is fast becoming a bit of a darling in the world of cloud - being
able to handle

Hi all,
I'm finally having performance issues with PostgreSQL when doing big
analytics queries over almost the entire database of more than 100gb of
data.
And what I keep reading all over the web is many databases switching to
columnar store (RedShift, Cassandra, cstore_fdw, etc) and having great
