This doesn't look like a hash containing an array to me.  The "ps" entries 
inside look like they're hashes, the key is "ps", the value is an array 
containing ["na vb", "ex anEx"]...

In any event, I think if you have value: stuff in YAML, it will decide it's a 
hash entry.  Array entries start with '-'.

If you don't care about the "ps" keys:

irb(main):004:0> puts ["at sf", "fc di", ["na vb", "ex anEx"],["na no", "ex 
otherEx", "pr pro"]].to_yaml
---
- at sf
- fc di
-
  - na vb
  - ex anEx
-
  - na no
  - ex otherEx
  - pr pro
