I've seen this kind of attitude a fair bit from postgres users and admins, especially as relates to replication. I was told it was a feature I didn't need, didn't really want, didn't understand, etc. I could accomplish the same thing by rsync, there were third-party patches to do it, etc. None of them actually solved the problem of wanting a live, hot spare that I could do reporting or reads against. Eventually they got defensive and hostile, accusing me of trolling or being a MySQL fanboy.

Now, of course, Postgres had a rudimentary replication implementation, and it's a great new feature and we're all excited about it, etc.

I'm not trying to say anything I'll about Postgres itself, or even the core developers, but this attitude doesn't always help.
