I completely agree. Initially, I was thinking of exposing the data to
user via HStore. But now, after Robert's suggestions, I think it will
be better to have an alternate representation. JSON seems to be an
excellent idea for that.

I am thinking of having the functions for working on the graph present
inside the data type itself.

I will definitely research that. Actually, I have never looked at
GIST/GIN code before, so I have no idea how they can be used here.
