[SQL] CONTEXT on PL/pgSQL

[Martin Marques]

I have a simple function made with PL/pgSQL and when I call it I get this in 
the logs:

2004-04-23 10:15:32 [30669] LOG:  statement: SELECT nodoSuperior(22) AS sup
2004-04-23 10:15:32 [30669] LOG:  statement: SELECT  $1
CONTEXT:  PL/pgSQL function "nodosuperior" line 7 at assignment
2004-04-23 10:15:32 [30669] LOG:  statement: SELECT  codigo,padre,nombre FROM 
procesos WHERE codigo= $1
CONTEXT:  PL/pgSQL function "nodosuperior" line 10 at select into variables
2004-04-23 10:15:32 [30669] LOG:  statement: SELECT   $1  IS NULL
CONTEXT:  PL/pgSQL function "nodosuperior" line 12 at exit
2004-04-23 10:15:32 [30669] LOG:  statement: SELECT   $1
CONTEXT:  PL/pgSQL function "nodosuperior" line 16 at return

What does CONTEXT mean, and is everything ok?

The function is this:

CREATE OR REPLACE FUNCTION nodoSuperior(INT) RETURNS VARCHAR AS '
DECLARE
COD INT;
SUP RECORD;

BEGIN

COD:=$1;

LOOP
        SELECT INTO SUP codigo,padre,nombre 
                FROM procesos WHERE codigo=COD;
        EXIT WHEN SUP.padre IS NULL;
        COD:=SUP.padre;
END LOOP;

RETURN SUP.nombre;
END;
' LANGUAGE 'plpgsql';
