Which DB abstraction ?

Hi, I am in a middle of the process of chosing which DB will be used for future projects. I've been using Mysql for almost 5 years (coupled with php of course) but it seems to have reached it's limits (actually the lack of some features). The other options include some traditional comercial dbs and postgresql. I am about to choose postgresql because it seems to support the features I need (foreign key, transaction, triggers, stored procedures) and is open source with active development. Even tough I'd like to receive (perhaps in private) personal thought about this decision I would not like to start a war...so my focus here is : which db abstraction layer is ready for use ? disavantages ? I am considering : Manuel Lemos' Metabase, Phplib and Pear. So far I've played a little bit with pear, and read about metabase and phplib with no real experience in both. The ideia is to start using it right away so the adption of other DB would be painless (almost). Thanks, RT __________________________________________________ Do You Yahoo!?
