That appears to require the port to still be installed:

$ port rdependents postgresql83
Error: Registry error: postgresql83 not registered as installed.

However, this doesn’t:

$ port echo rdependentof:postgresql83

That produces no output on my system so perhaps it only deals with installed packages.

This, on the other hand, lists all ports depending directly on postgresql83, regardless whether they’re installed or not:

$ port echo depends:postgresql83
