globally disabling protect identifiers

I'm using oci8 but that shouldn't matter. Having cross db support is a fundamental requirement for all frameworks. My foo bar db query example should work on all dbs regardless of what type of db it is.

$db['default']['hostname'] = "//192.168.1.4/DEV0";
$db['default']['username'] = "mydev";
$db['default']['password'] = "not going to post this on a forum";
$db['default']['database'] = "";
$db['default']['dbdriver'] = "oci8";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
