Catalog permissions

Hi,

I have to allow one user to use my Postgres installation in one schema of several. We are preparing an phpPGAdmin installation to give an remote access to this schema.
The phpPDAdmin is showing the entire catalog to this user and allowing access only in the schema that I gave permissions to him.
How do I do to this user can see only the schema that he has access, not the entire catalog.
Is it possible?
Thanks,
Bruno
