where did debug_print_query go in 7.3???

How come debug_print_query isn't in 7.3??? I need that to develop my application.

Also the docs haven't been fully updated. runtime-config.html has:

DEBUG_PRINT_PARSE (boolean)
DEBUG_PRINT_REWRITTEN (boolean)
DEBUG_PRINT_PLAN (boolean)
DEBUG_PRETTY_PRINT (boolean)

     These flags enable various debugging output to be sent to the server log. For each
executed query, print 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.
