Heroku announces support for 17 new Postgres extensions

I was hoping for postgis when I saw the title . Hopefully that's coming soon.

Since the dblink extension is available even on the free dev plan, is anything stopping you from creating a bunch of dev databases and linking them together to overcome size restrictions? Sounds kinda fun, although there will of course be concerns over performance, integrity constraints, etc.

Is Postgres gaining momentum such that it might displace MySQL as the go-to DB?

According to the Postgres documentation, CHKPass is implemented on top of the crypt() unix function.<p>More details would be welcome... What hashing function are you using at Heroku? Short of bcrypt, all it gives is a false sense of security.<p>As is, it sounds more dangerous than useful.

Any performance benchmarks of pgsql on heroku?

ltree looks awesome. I didn't know it was in there.
