Re: [HACKERS] Subscription code improvements

0002 looks like a good improvement to me.  The existing routine is
messy, and apparently it's so just to save one LockSharedObject plus
cache lookup; IMO it's not worth it.  Patched code looks simpler.  If
there are cases where having the combined behavior is useful, it's not
clear what they are.  (If I understand correctly, the reason is that a
sync worker could try to insert-or-update the row after some other
process deleted it [because of removing the table from subscription?]
... but that seems to work out *simpler* with the new code.  So what's
up?)
