Does postgresq database supports reading data from the same table from many observable simultanousely?
Hi,
I don't know if is it the suitable place to ask my question but I want to
know if a table in a postgres database enable multiple reading actions for
mayn rxjs observbles or not.
I create two observables that need to access the same table simultanously
to get data, but I found that only one of them receive data.
I'm not sure if the problem may be come from the database or not that's why
I asked my question.
Best regards.

Not sure if i understand your question. But for sure PG is able to serve multiple clients at the same time.

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.

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

Yes but it will happen serially.
