Description

When IMPALA-5821 is complete, it will change the output from 'explain ...' when EXPLAIN_LEVEL is extended or higher. The header will now contain a line showing the query, with implicit casts as part of the text. This should probably be documented in docs/topics/impala_explain_level.xml
