我想跟踪函数内的执行时间。例如，我有以下状态跟踪表：

    CREATE TABLE status_table
    (
    run_id numeric NOT NULL,
      start_ts timestamp(6) without time zone NOT NULL,
      end_ts timestamp(6) without time zone NOT NULL
    )
WITH (
  OIDS=FALSE
)
DISTRIBUTED RANDOMLY;

我有以下示例函数，它使用 PG_SLEEP(5) 作为对我的函数实际执行操作的模拟：

CREATE OR REPLACE FUNCTION wrapper_func(p_run_id numeric)
  RETURNS numeric AS
$BODY$
Declare  
tmp_start_ts timestamp(6) without time zone;
tmp_end_ts timestamp(6) without time zone;

BEGIN
tmp_start_ts := CURRENT_TIMESTAMP;
PERFORM PG_SLEEP(5);
tmp_end_ts := CURRENT_TIMESTAMP;
INSERT INTO status_table (run_id,start_ts,end_ts) VALUES (p_run_id,tmp_start_ts,tmp_end_ts);
RETURN 0;
END;
$BODY$
  LANGUAGE plpgsql VOLATILE;

I then called this …
