I dont have the replication setup on my machine right now but I guess as far as I remember you can surely check for the master and slave nodes from a Slony schema table.
I am using LinuxHA to manage the failover and Slony as part of to failover to move to the healthy node. But my question was more along the lines, if a user has access to both databases (master and slave) but does not know which one is which, how can you tell?
Take a scenario: you configure 2 servers as master and slave. You walk for a period of time during which a number failovers occur. You come back. Can I query a sl_???? table to determine which server is the current master and which one is the current slave?
Thank you,
Slawek
