[Typo3] T3 on PostgreSQL

[Marcel Douwstra]

I was wondering, sparked by this thread, why no database abstraction 
layer is used in Typo3?
And moreso, if no abstraction layer is used, why should I/we bother 
with using the typo3 functions for database access?
I have been having some problems using them (especiallly annoying with 
the inconcistancy between exec_query and exe_MM_query) but I believed 
this was needed to keep things scalable. But when you look in the core 
you see that all those typo3 functions are just a simple library that 
access mysql functions directly.
This kinda explains to me why a load of extensions use mysql functions 
directly (I believe I even saw Kasper doing so in a tutorial).

So again, concretely these 2 questions :

- Why is there no database abstraction layer in typo3?
- Why should we use the t3lib_DB functions if this doesn't really 
improve the scalability of your extension?

Cheers,

Marcel
