readonly user

<div style="font-family: Verdana;font-size: 12.0px;"><div><div>Dear List,</div><div> </div><div>i work with a
PostgreSQL/PostGIS-database(version 9.1.14/1.5.3) to manage geodata and other data.</div><div> </div><div>Now i want to
createa login-role, that only enable readonly rights for the data. I easy find hints to the GRANT-command and i created
alogin-role "readonly" and modify the permissions of the role with this commands.</div><div> </div><div>GRANT CONNECT
ONDATABASE the_db TO readonly;</div><div>GRANT USAGE ON SCHEMA public TO readonly;</div><div>GRANT SELECT ON ALL TABLES
INSCHEMA public TO readonly;</div><div>GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO readonly;</div><div>GRANT
EXECUTEON ALL FUNCTIONS IN SCHEMA public TO readonly;</div><div> </div><div>This works fine since i edit columns of
tablesor e.g. load new Shapefiles in the database. The readonly-role did not get the changes and i have to GRANT the
Permissionsagain.</div><div> </div><div>My question is: Is it possible to GRANT Permissions for existing and new or
changedObjects in the database.</div><div> </div><div>I only find this
link.</div><div>http://wiki.postgresql.org/images/d/d1/Managing_rights_in_postgresql.pdf</div><div> </div><div>Part7.2

view,but it does not work.</div><div> </div><div>I also have a look in some manuals but i dont find any solution for my
