I'm a real fan of PostGIS and like ltree and hstore a lot. Heroku isn't quite right for my needs at this time, but I would definitely consider it if I had a use case that needed an extremely fast public facing postgres installation.
I am curious as to whether you do pro-rated pricing?
@Olefoo you can get PostGIS on Heroku via SpacialDB. SpacialDB is cloud hosted PostGIS and a convenient RESTful API. We have a heroku addon too currently in private beta. Check out our devcenter here: http://devcenter.spacialdb.com/ and let us know if you would like a beta invite.
That is interesting, there are times when I want to use PG as an ETL tool and take a midsized ( < 2tb data ) set and load it up and slice and dice it and produce some output for other programs and then have it go away. So, I'll keep you guys in mind.
