Right, I wasn't trying to capture everything, just enough to give the user a reasonable indication of what went wrong.
Mypatch was designed around the idea that the user would need to figure out how to fix the subscriber side prior to
re-enablingthe subscription.  As such, I wasn't bothered with trying to store everything, just enough to give the user
aclue 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?
