Erik, Adrian,

The trigger function is very long and complex (and not yet well
documented), but bind_action is a normal function callable everywhere, the
problem as discovered by Erik was in the null value contained in the hstore.

Anyway, when the ecosystem of functions will work correctly I can share, so
you can give me how improve :-D
