user name lost from dictionary

Hi Every Body!

I would like to know if someone has seen the behavior described
below.

By considering a DLL like this:

CREATE TABLE "recursos_materiais" (
"nr_rec_mat" smallint NOT NULL,
"dc_rec_mat" character varying(100),
"in_situacao_rec_mat" character(1),
Constraint "recursos_materiais_pkey" Primary Key ("nr_rec_mat")
);

REVOKE ALL on "recursos_materiais" from PUBLIC;
GRANT ALL on "recursos_materiais" to "user_fomacao_des"; --< Here is the
point in question

And after mounths of work on postgresql you get a error stating that you
do
not have privileges access on "recursos_materiais" because
you checked this has happend:

CREATE TABLE "recursos_materiais" (
"nr_rec_mat" smallint NOT NULL,
"dc_rec_mat" character varying(100),
"in_situacao_rec_mat" character(1),
Constraint "recursos_materiais_pkey" Primary Key ("nr_rec_mat")
);

REVOKE ALL on "recursos_materiais" from PUBLIC;
GRANT ALL on "recursos_materiais" to "131"; --< What is it?

Is that a bug?
