I agree.  From what I've seen, the lack of good incremental backup is
still a major problem regarding adoption of large-scale systems.
Similarly, upgrade-in-place makes using PG fairly prohibitive in
several cases, though I'm glad Zdenek et al. are working on that.  I
still hear lots of questions regarding, "how do I tell what PG is
doing right now?", which is why we (EnterpriseDB) developed RITA (the
Runtime Instrumentation and Tracing Architecture).  DTrace is great,
but it's not cross-platform, can't be queried from within the
database, and until now, didn't really give you enough information to
diagnose many user-related problems.

Agreed.
