What makes you say this is a useless demo? I can't count the number of people who've struggled to do analytics inside of Postgres. Almost always they end up setting up a separate system such as Clickhouse and replicating the data between the two systems. Now they can have one system that's Postgres-compatible, and it's faster than either of the original systems.

In our last post[0], when we mentioned we were getting close to Clickhouse level performance (now faster than Clickhouse), we were met with disbelief. This post is meant to explain part of how we closed the 300x gap between Postgres and Clickhouse. The execution model being 10x of it.
