relation does not exist!?

Just installed postgresql today - I keep getting the error "relation ... 
does not exist"
when I try some simple selects. This is the scenario:

Created a user X and a schema by the same name X using pgAdmin (pg 8.0.3) , 
and set
the user as owner of the schema.
Then I created a table Y under schema X, and set user X as owner of the 
table. Then
I put some rows in the table.
As postgres user when I try "select * from Y" I get the error "relation Y 
does not exist".
I have tried "select * from X.Y", same error. The I tried logging in as X 
and executing the
select, but still get the same error. I have also tried the same select from 
a Java program
using JDBC and get the same error. What am I doing wrong?
