How difficult is it to replace MySQL with PostgreSQL in RubyStack and jRubyStack?

I’m interested in using RubyStack or jRubyStack (most likely jRubyStack), but I want to use PostgreSQL instead of MySQL. So:

1. Would BitNami have such a stack on their roadmap already? If not, who else would want it?
2. How difficult would it be for me to swap out MySQL and swap in PostgreSQL?

Hi,

Would BitNami have such a stack on their roadmap already? If not, who else would want it?

We discussed the possibility some time ago, but decided at the end that there are higher level tasks that we need to perform before this one.

How difficult would it be for me to swap out MySQL and swap in PostgreSQL?

This is not possible, as you would need to rebuild (configure and compile) the whole stack.
