I'm assuming you are accessing PostgreSQL via RX Javascript?
If that is the case, then this question has nothing to do with PostgreSQL and is a question for whatever RXJS implementation you are using.

But is it possible to make simultanoues select queries from the same connection?

Connections are synchronous. You can have multiple connections to the database at a time.
