Yes, most people don't care much about writing database independent code,
because they assume they will never need to switch from their current
database of choice.
This is often not the case. Many developers that started with lower end
database like MySQL and PostgreSQL often realize that they need their
databases to scale up to a point that you will need an high end database to
handle.
Other developers find themselves in the opposite migration way. They
develop products that rely on specific high end databases but then they
realize that there is a much wider audience of low end database users that
could be interested in their products if they could work with those
databases.
This uncertainty of the future needs lead me to start developing Metabase
two years ago. Metabase is a PHP database abstraction package that you may
rely to write database independent applications. It features not only
database independent access but also database independent schema
installation.
Metabase is free and you may want to look at it here:
