Hi everyone,
Does anyone know a random query generator for Postgres? Something that gets
my schema and, based on that, generates hundreds of different queries with
join, group by, etc.
Thank you.

I'm sure they will!
Thank you, Oleg.

Interesting! Was this presentation filmed? Or would you have a post or
something else with more details?

ators and their cost. The thing
is that I haven't found any work using PostgreSQL, so I'm struggling to
adapt it.
My question is if anyone is aware of a work that uses machine learning and
PostgreSQL to predict query runtime, or maybe some other method to perform
this.
Thank you.
