What visualization is that you are using? Also what do you mean by 2 postgresql requests, I think that might be the issue 2 queries?

I use stat panel, but same with other visualisations.
And yes, i mean 2 queries.

But it works with MySQL queries. I have 2 MySQL queries, and I can do some operations between them.

very interesting! I think it is a bug! submit it as such
the other option is to do it all in one query window also you can try?
