And frankly you are making unsubstantiated complaints about the developers, to 
whom you have not talk, not hear speak, and wouldn't listen to if you did.  
There are not, for a start, bits and pieces all over the place.  The data is 
stored according to an ISO - I don't recall the number - unlike earlier 
versions.  I've no doubt that someone will write about using Postgreslql at 
some point, but you would be wiser to learn to understand the system as it is 
set up by default before trying to be clever and write your own version.  
After all, it is only 4 years or so that a team of developers, some of them 
full-time on this project, have been working on it, so go ahead.  Write your 
this weekend.
