From 02cef11885bee0e5b3671ff35908d9605d7ebcaf Mon Sep 17 00:00:00 2001 From: glyn Date: Fri, 14 Oct 2016 16:17:08 +0100 Subject: [PATCH] Make compatible with pg9.6+ pg_stat_activity view. However 9.6 brings the idle_in_transaction_session_timeout setting which is a much better alternative to this function. --- pg_long_xact_9.1+.plpgsql | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/pg_long_xact_9.1+.plpgsql b/pg_long_xact_9.1+.plpgsql index 15b9da4..2d1926a 100755 --- a/pg_long_xact_9.1+.plpgsql +++ b/pg_long_xact_9.1+.plpgsql @@ -28,9 +28,9 @@ BEGIN COALESCE(client_addr || \':\' || client_port, \'[local]\') AS client,' || CASE WHEN (v_srv_version < 9.2) THEN E'current_query, \'[not supported]\' AS state, ' ELSE 'query AS current_query, state, ' END || E'current_timestamp-xact_start AS runtime_int, - extract(EPOCH FROM current_timestamp-xact_start) AS runtime, - waiting - FROM pg_stat_activity + extract(EPOCH FROM current_timestamp-xact_start) AS runtime,' || + CASE WHEN (v_srv_version < 9.6) THEN 'waiting, NULL::text AS wait_event, NULL::text AS wait_event_type ' ELSE 'wait_event IS NOT NULL AS waiting, wait_event, wait_event_type ' END || + E'FROM pg_stat_activity WHERE current_timestamp-xact_start > \'' || in_duration || E'\'::interval' || ' AND datname = current_database() ORDER BY waiting ASC, runtime DESC;' @@ -94,8 +94,8 @@ BEGIN END IF; IF FOUND THEN - v_line := format(E'long_xact waiter pid: %s blocker detail is; pid: %s duration: %s ms relation: %s lock type: %s user: %s application: %s client: %s statement: %s', - v_xact.pid, v_blk_xact.blk_pid, v_blk_xact.blk_runtime, v_blk_xact.blk_relation, v_blk_xact.blk_type, v_blk_xact.blk_usename, v_blk_xact.blk_app, v_blk_xact.blk_client, v_blk_xact.blk_query); + v_line := format(E'long_xact waiter pid: %s wait type: %s blocker detail is; pid: %s duration: %s ms relation: %s lock type: %s user: %s application: %s client: %s statement: %s', + v_xact.pid, CASE WHEN (v_srv_version < 9.6) THEN '[not supported]' ELSE COALESCE(v_xact.wait_event_type,'N/A')||':'||COALESCE(v_xact.wait_event,'N/A') END, v_blk_xact.blk_pid, v_blk_xact.blk_runtime, v_blk_xact.blk_relation, v_blk_xact.blk_type, v_blk_xact.blk_usename, v_blk_xact.blk_app, v_blk_xact.blk_client, v_blk_xact.blk_query); CASE lower(in_raise_type) WHEN 'notice' THEN RAISE NOTICE '%', v_line; -- 2.39.5
