+ * The CONN_TRX_AUTO flag is ignored for databases with ATTR_DB_LEVEL_LOCKING
+ * (e.g. sqlite) in order to avoid deadlocks. ILoadBalancer::getServerAttributes()
+ * can be used to check such flags beforehand.
*
* If the caller uses $domain or sets CONN_TRX_AUTO in $flags, then it must also
* call ILoadBalancer::reuseConnection() on the handle when finished using it.
*
* The handle's methods simply wrap those of a Database handle
