Subject: Restricting columns by users
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hello,
I'm looking for a method to restrict columns by users on postgresql, 
searching in google I found what I want, but in mysql, below I reproduce 
the paragraph that shows what I exactly want:

"MySQL can also restrict access on the table level and even on the 
column level. What this means is that a user can have zero privileges on 
a database, but can have all privileges on a table in that database. 
Alternatively, a user can have zero privileges on a database, restricted 
privileges on a table, and all privileges on any particular column on 
that table. This is done by inserting records into the TABLE_PRIV table 
and the COLUMN_PRIV table."

Exist something like it for postgresql?

Thanks
