I'm using Postgres 8.4 and Slony 1.2.20. 

My database replication configuration is a master with two slaves. 

I have a table "A" that is replicated. A trigger existed on table "A" that called a function that inserted into another table "B" that was replicated. 

I don't need to replicate table "B" anymore. I've removed it from the replication set. 

I'd like to clean up the trigger and function as well but, although I can easily drop these on the master, the slave trigger is hidden by slony. 

What is the approach used to drop unneeded triggers from slaves? 

Thanks,
Frank
