Right, I wasn't trying to capture everything, just enough to give the user a 
reasonable indication of what went wrong.  My patch was designed around the 
idea that the user would need to figure out how to fix the subscriber side 
prior to re-enabling the subscription.  As such, I wasn't bothered with trying 
to store everything, just enough to give the user a clue where to look.  I 
don't mind if you want to store more information, and maybe that needs to be 
stored somewhere else.  Do you believe pg_subscription_rel is a suitable 
location?
