please, allow me to rephrase my point:
if two tools compete for the same "job" they are mutually exclusive.
in case of Erlang+Postgres: Postgres provides you very nice application
server, while Erlang provides you interesting means of data storage.
either one has its advantages and its drawbacks.
while the combination of them provides you all the drawbacks of both.

Exactly what i do all the time! and i have never met anyone to agree
with me on the point :)

this is why i delegate all "password handling" and "money jobs" to pg.
to the extent of eliminating any scripting between pg and nginx.

it sounds logical, but i can not imagine how is it practically possible
to keep these two subsystems *so* isolated (independent)...
