Most of our applications require write access in some shape or form, so at least the default replication of Amazon RDS doesn't cut it. Besides that we don't really need it so far, don't see the need for it in the coming months either.
- bearhandsly 12y agoSimple but sensible.
- hugopeixoto 12y agoOne problem I have with postgres right now is that whenever I want to upgrade the cluster (say from 9.1 to 9.3) there's downtime while the cluster is upgraded. Not even vanilla replication helps, right now. I think I'd have to use something like slony to replicate between different versions of postgresql, but I never tried it. How does upgrading postgresql versions work in RDS?
