It's quite possible that in trimming my messages for posting I'm removing
too much of the context; is that the case? To recap:
- you pointed out that there was an incompatibility.
- I pointed out a way in which that incompatibility can be substantially
reduced in scope, from affecting "everyone who has views defined using
add_missing_from" to only affecting "everyone who has views defined using
add_missing_from but who has subsequently turned that off, in spite of the
bugs that they would encounter in doing so".
- you respond by saying there is an incompatibility.
Now, I don't know how I can possibly be clearer about this. I know that
changing the default add_missing_from causes an incompatibility. If you
prefer to keep it, rather than use a solution which will work for everyone
who (a) isn't already vulnerable to dump+restore problems and (b) will use
8.1's pg_dump to upgrade, then personally I couldn't care less. I'm just
surprised by the attitude.
