Don't you still need to purchase citus DB to use this?
We open sourced cstore_fdw with the Apache license. You can just build and load the extension, and start using it with your PostgreSQL 9.3+ database.
If you later need to scale out your PostgreSQL cluster, just please let us know. :)
Thank you very very much in advance. This is a really huge deal. Even for general things like academic research. We shall see.
