Here is an example :

CREATE OR REPLACE FUNCTION test.pruebas_tmp(pnumtablas integer)
RETURNS integer AS
$BODY$
DECLARE
lresp3 integer:=1;

begin
while lresp3<=1 loop --pnumtablas loop

begin
delete from tmp_tablaprueba1;
EXCEPTION
WHEN UNDEFINED_TABLE THEN
begin
RAISE NOTICE 'Before create ';
create temporary table tmp_tablaprueba1 (campo1 integer, campo2 integer, campo3 numeric(1,0), campo4 smallint, campo5 varchar(6) ) ON COMMIT DROP;
EXCEPTION
WHEN INTERNAL_ERROR then
RAISE NOTICE 'caught internal error';
end;
end;

RAISE NOTICE 'After control . . .';

lresp3:=lresp3 + 1;

end loop;

return lresp3;
end;
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION test.pruebas_tmp(integer) OWNER TO desarrollo;

From Pg_Admin I open a SQL Window and execute "select test.pruebas_tmp(1);"
I received the expected messages.

NOTICE: Before create
NOTICE: After control . . .
Tiempo total de ejecución de la consulta: 180 ms.
1 fila recuperada.

From this window I opened another one and from there I executed the same sentence.

I opened many windows and did the same until I got the error with this messages.

NOTICE: Before create
NOTICE: caught internal error
NOTICE: despues del control . . .
Tiempo total de ejecución de la consulta: 60 ms.
1 fila recuperada.

Without error control I got this message :

NOTICE: Before create
ERROR: could not find tuple for attrdef 259154466

campo1 integer,
campo2 integer,
campo3 numeric(1,0),
campo4 smallint,
campo5 varchar(6)
) ON COMMIT DROP"

********** Error **********

Thanks for your help.
