Postgres PL/Python

[Ksenia Marasanova]

Thanks to all, especially to Stuart, for very informative answers.

It's clear to me now that  there is no need in my case to use
functions / stored procedures (yes, with typical MVC app I meant a
webapp on the same server with database, administered by the same
persons). However it can be a useful addition for more complex
situations that may come.
