So, what's still missing in postgres?

To make the responses as constructive as possible, please also specify:

* Whether you currently use postgres, and what other systems you use (presumably ones that do have the feature that is missing in postgres)

* Whether you currently need the feature, or whether you anticipate the need in the future, or whether you expect that other people will need it

* Whether the missing feature is preventing you from using postgres, or just a significant pain point (which could include ease-of-use issues)
