Re: Hot to restrict access to subset of data

I believe you can probably use views to accomplish this.

You create a view that is populated based on their username. Then you  
remove access to the actual table, and grant access to the view.

When people look at the table, they will only see the data in the  
view and will not have access to the other.

Of course, this assumes they do not need to update the data. I've not  
played around with rules to make a view allow updates. I believe it  
is possible, I've just not done it yet. This also assumes you have  
data somewhere that maps user names to document types.

The postgresql docs should provide the syntax and additional details  
if you want to try this. I have also found pgAdmin very useful to  
create views and other schema related activities as well.

Hope this helps,
Greg
