Problem with insert related to different schemas

Hi Everyone,

I've come along with a problem that appeared with latest version of
Postgresql 8.4.2.

I'm trying to insert a row in the analysis schema:

INSERT INTO
"analisys"."response_quality" ("uuid","id_survey_question","id_survey","id_survey_status","id_shop","survey_question_response","id_survey_answer","date_survey_answer") VALUES ('83968de5-eac7-4f52-bbec-7392a198f556',7,1,1,16,3,9987,'2009-12-01 00:00:00.000000 +01:00:00')

But it fails because:

ERROR: permiso denegado al esquema public
LÍNEA 1: SELECT 1 FROM ONLY "public"."survey_question" x WHERE "id_su...
^
CONSULTA: SELECT 1 FROM ONLY "public"."survey_question" x WHERE
"id_survey_question" OPERATOR(pg_catalog.=) $1 FOR SHARE OF x

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

ERROR: permiso denegado al esquema public
Estado SQL:42501

Surely it may have something to do with foreign keys.

But the user who executes this query has access to all foreign keys
tables...

Then why I'm receiving this error?

Thank you in advance!
