How to query "primary_slot_name" in slave server?

[Edson Richter <edsonrichter@xxxxxxxxxxx>]

Hi!

I've been searching over the net, but cannot find a reference.

I know that in server I can execute "select * from pg_replication_slots" and get all created slots.

But how can I query slave to know wich primay slot it is connecting to?

Thanks in advance,

Edson
