We're currently deploying most of our apps with postgres 8.3 and 8.4. I've noticed postgres 9.x has several major improvements like replication and so on. Does someone actually have any experience with mendix in combination with postgres 9.x and share their thoughts about this subject? I'm curious about the pros and cons.
I did some projects on postgres 9 and did not encounter any problem (except that converting postgres 9 db to 8.4 is a bit of hassle).
