User access

Hi,

I have just started looking at roles on a database.

I have a few schemas and would like to  revoke access for a user on
some functions and tables in the schema and grant access to other
functions and tables in the schema.

I have tried to grant the access to the functions but then when that
user tries to call the funciton it says that he does not have access
to the schema. So I've tried to GRANT USAGE on the schema but then the
user have access to all the functions in the schema. So lastly I have
treid to revoke usage from a function but the user can still call the
function.

How should I approach this?

It seems to work fine for tables. To GRANT USAGE on the schema and
then GRANT or REVOKE SELECT on some of the tables.
