Hey, you don't have to tell me that it's a pain.  I was just
giving you another way to do the same thing.

Everyone has to rant once and a while ;)  Anyway, there is hope
in all of this.  The PostgreSQL development team could build
support for it in some newer versions.  And it's open source so
even you could hack the functionality it if you want.  Hey, I'd
do it myself if I had the time and motivation.  In the meantime
we'll just have to wait I guess.
