I do have to add that this list of requirements sounds very much like a set supplied by the sales organization of a
commercialdatabase vendor (in fact, a particular commercial database vendor) in order to exclude open-source software.
Open-sourcesoftware relies very much on a whole ecosystem, rather than attempting to deliver every imaginable feature
inthe core distribution.  This is especially true of projects like PostgreSQL which are not backed by a single company
anddo not have an official commercial distribution.  Can your client articulate why they need these specific features,
andwhy they must be in the core distribution?
