Re: query has no destination for result data

I believe language plpgsql is not considered part of the function body
so it is not included in the line count:

https://www.postgresql.org/docs/10/plpgsql-structure.html

When tracking a line number down I usually do:

\ef some_function line_number

which counts the line in the function body not the file. So for example:

Using set nu in Vi:

1 CREATE OR REPLACE FUNCTION public.ts_update()
2  RETURNS trigger
3  LANGUAGE plpgsql
4 AS $function$
5 BEGIN
6     NEW.ts_update := timeofday();
7 RETURN NEW;
8 END;
9 $function$

\ef ts_update 4

CREATE OR REPLACE FUNCTION public.ts_update()
  RETURNS trigger
  LANGUAGE plpgsql
AS $function$
BEGIN
     NEW.ts_update := timeofday();
RETURN NEW;  <--- This row is marked
END;
$function$
