Is this available on 7.1.3?
I did:
drf=# set show_query_stats = TRUE;
drf=# set debug_print_query = TRUE;
drf=# select horse,fd from horses limit 1;
horse | fd
-------------------+----
a big kahuna* | d
drf=# show debug_print_query;
NOTICE: debug_print_query is on
drf=# show show_query_stats;
NOTICE: show_query_stats is on
The variables were on, yet I didn't get the debug output.
