[chef] Overriding attributes

[Jeffrey Jones < >]

Hello all

I have a list of default users I would like for my DB and am attempting 
to combine them with ones set in an attribute.json file used by chef 
solo. The relevant code is below

https://gist.github.com/rurounijones/5883385

If there is nothing set in the json file then it write the 3 default 
values to pg_hba.conf

However if there are values set in the json then ONLY the values in the 
.json file are used. They are not merged in with the default_db_users 
despite my setting of them (I tried everything up to force_override 
which, as far as I see it, should take precedence),

Am I missing something here?

Cheers

Jeff
