In terms of overall adoption, PostgreSQL doesn't need to catch Oracle or MySQL. The people that enjoy legacy platforms are not going to change (necessarily). Real work gets done with PostgreSQL. You can't buy something from Amazon.com without using PostgreSQL. The more Amazon talks about that in their ecosystem, the more PostgreSQL becomes the default choice for all new developers within that (very large) ecosystem. When you combine that with the loud presence of another 800lb Gorilla promoting PostgreSQL (MSFT), the market has spoken.
