If someone check PECL site for PDO you will see:
http://pecl.php.net/package/PDO
that PDO extension are already STABLE since 2006.
When you run EA3 for install these extension you will get this warning:
(UNSUPPORTED EXPERIMENTAL) Includes SQLite support. Other drivers (freetds, oracle, etc) can be installed with PECL. If you use rawopts to add them during compile then you will have to have them '=shared' and *NOT* do the PHP "versioning" option. Custom opt mods for PDO extensions should also do the "versioning" logic this one does.
What this means? Is it still experimental? Installing this on a production server will make my server down every 3 days?
I have several costumer that need PDO for Magento and so I need to install these extension but i don't want to have server with buggy PHP.
Thank you
