Jonathan mentioned the _rowsource_execution_statistics parameter, this is a boolean parameter and could be set with dbms_system.set_bool_param_in_session.

Btw, from 10g there is a _rowsource_statistics_sampfreq parameter, which could control the performance impact (and accuracy) of gathering rowsource statistics. I haven't done any tests with it though...
