It's been a few years since I worked with slony, and you did not state which version of slony or PostgreSQL you are working with, nor did you indicate the O/S.

I think OP had pointed to using streaming....

That being said, you should be able to formulate a query with a join between sl_path & sl_node that gives you the information you need.

Hi,

On an hot standby streaming server, is there any way to know, in SQL, to know the ip of current master ?
The solution I have is to read the recovery.conf file to find primary_conninfo, but, it can be false.

I've run into this as well. Only way is recovery.conf.

9.6 onward you will have a new view which will facilitate you to query the replication details on standby.

I have not tried but probably you can check the pid of wal receiver and find out what host it is connected to (should be possible from network stats).
