Re: JOIN on partitions is very slow

Are you able to tweak the query or is that generated by an ORM? What version of Postgres? Which configs have you changed from default? How many partitions do you have? Is there an index on company name?

Anytime I see distinct keyword, I expect it to be a performance bottleneck and wonder about rewriting the query. Even just using group by can be much faster because of how it gets executed.
