<para>
For any executed query, prints either the query, the parse
tree, the execution plan, or the query rewriter output to the
server log. <option>DEBUG_PRETTY_PRINT</option> selects are
nicer but longer output format.
These flags enable various debugging output to be sent to the
server log. For each executed query, prints either the query text,
the resulting parse tree, the query rewriter output, or the execution
plan. <option>DEBUG_PRETTY_PRINT</option> indents these displays
to produce a more readable but much longer output format.
Setting <option>DEBUG_LEVEL</option> above zero implicitly turns
on some of these flags.
