Neat! It doesn't work on Oracle, but you implied that it's PostgreSQL-specific so I somewhat expected that. It's a lot cleaner than mine and, even though it's not something I've seen before, it's fairly obvious what it's going to do. When I did my testing I did it on Oracle since I have it available at work. For my non-work projects I use PostgreSQL and, for the most part, find that I can flip between the two database without too much trouble. Of course, this also means that I don't know about some PostgreSQL niceties like what you showed.
