Does this do what you want ? Note that the "QUERY STATISTICS" are log output, and not a part of the sql result. $ psql postgres -Atc "SET client_min_messages=log; SET log_statement_stats=on" -c 'explain analyze SELECT max(i) FROM generate_series(1,999999)i' SET LOG: QUERY STATISTICS DETAIL: ! system usage stats: ! 0.625402 s user, 0.059799 s system, 0.687496 s elapsed !
