On that page there's a note about 9.6. Did you see the referenced commit https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=52f5d578d6c29bf254e93c69043b817d4047ca67 ? Maybe see about using the "pg_blocking_pids(int) returns int[]" function instead. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
