I was curious and the list did not disappoint: https://postgres.heroku.com/pricing

With that said I'm not sure how squid managed to be more dangerous than a kappa. >Kappa are usually seen as mischievous troublemakers. Their pranks range from the relatively innocent, such as loudly passing gas or looking up women's kimonos, to the malevolent, such as drowning people and animals, kidnapping children, and raping women

I checked with some Japanese, the word on the street is that Kappa's are pretty innocuous

It's kind of a love-hate relationship. They can be trouble when they're feeling mischievous, but if they're happy they'll help you out. The Japanese will leave gifts at Kappa shrines, just in case.

The best gift is cucumber, which the Kappa can't resist. Don't go swimming in Japan after eating cucumber, because they will drown you when they smell it on you.
