/**
* Set the adapter's profiler object.
*
* The argument may be a boolean, an associative array, an instance of
* Zend_Db_Profiler, or an instance of Zend_Config.
*
* A boolean argument sets the profiler to enabled if true, or disabled if
* false. The profiler class is the adapter's default profiler class,
* Zend_Db_Profiler.
*
* An instance of Zend_Db_Profiler sets the adapter's instance to that
* object. The profiler is enabled and disabled separately.
*
* An associative array argument may contain any of the keys 'enabled',
* 'class', and 'instance'. The 'enabled' and 'instance' keys correspond to the
* boolean and object types documented above. The 'class' key is used to name a
* class to use for a custom profiler. The class must be Zend_Db_Profiler or a
* subclass. The class is instantiated with no constructor arguments. The 'class'
* option is ignored when the 'instance' option is supplied.
*
* An object of type Zend_Config may contain the properties 'enabled', 'class', and
* 'instance', just as if an associative array had been passed instead.
*
* @param Zend_Db_Profiler|Zend_Config|array|boolean $profiler db profiler
* @return Zend_Db_Adapter_Abstract Provides a fluent interface
* @throws Zend_Db_Profiler_Exception if the object instance or class specified
* is not Zend_Db_Profiler or an extension of that class.
