In BC, 'competitive salary' ranges from 40-160K for the same role :)
Your table is conveniently lacking the salary ranges I've been offered from over a dozen higher paying companies in the city...
In fact, not a single company that pays well whom I've talked to is on your list other than Amazon and Microsoft (Whom will pay a whole lot more if you point the spread out to them).
I've experienced this time and time again. Postgres is an outstanding database for most use cases. I also love all the enhancements it has been getting over the last twenty four months.

I think it fits in with his immediate solution to everything angle that's completely nuts when you stop to think about it.
