Hello I propose enhancing GET DIAGNOSTICS statement about new field PG_CONTEXT. It is similar to GET STACKED DIAGNOSTICS' PG_EXCEPTION_CONTEXT.
Motivation for this proposal is possibility to get call stack for
debugging without raising exception.
This code is based on cleaned code from Orafce, where is used four
years without any error reports.
CREATE OR REPLACE FUNCTION public."inner"(integer)
RETURNS integer
LANGUAGE plpgsql
AS $function$
declare _context text;
begin
get diagnostics _context = pg_context;
raise notice '***%***', _context;
return 2 * $1;
end;
$function$
postgres=# select outer_outer(10);
NOTICE: ***PL/pgSQL function "inner"(integer) line 4 at GET DIAGNOSTICS
PL/pgSQL function "outer"(integer) line 3 at RETURN
PL/pgSQL function outer_outer(integer) line 3 at RETURN***
CONTEXT: PL/pgSQL function "outer"(integer) line 3 at RETURN
PL/pgSQL function outer_outer(integer) line 3 at RETURN
outer_outer
─────────────

(1 row)
Ideas, comments?
Regards
