-        For any executed query, prints either the query, the parse
-        tree, the execution plan, or the query rewriter output to the
-        server log. DEBUG_PRETTY_PRINT 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. DEBUG_PRETTY_PRINT indents these displays
+   to produce a more readable but much longer output format.
+   Setting DEBUG_LEVEL above zero implicitly turns
+   on some of these flags.
