Global apr_dbm_open_ex (apr_dbm_t **dbm, const char *type, const char *name, apr_int32_t mode, apr_fileperms_t perm, apr_pool_t *cntxt): In apr-util 0.9 and 1.x, the type arg was case insensitive. This was highly inefficient, and as of 2.x the dbm name must be provided in the correct case (lower case for all bundled providers)
