delete query using CTE

Hello, trying to use CTE to remove duplicates from a table. The DELETE
version does not work, but the SELECT version does, so I am not
understanding what the problem is. Any suggestions on how to fix it?

Here is my query:

WITH cte AS
( SELECT *, ROW_NUMBER() OVER ( PARTITION BY ticker, date ORDER BY ticker,
date) my_row_num FROM price_old)
DELETE FROM cte WHERE my_row_num > 1;

I get the following error:

ERROR: relation "cte" does not exist LINE 3: DELETE FROM cte WHERE
my_row_num > 1;

But when I run change the query to a select query it runs fine (in that it
returns all the duplicate rows). For example:

WITH cte AS
( SELECT *, ROW_NUMBER() OVER ( PARTITION BY ticker, date ORDER BY ticker,
date) my_row_num FROM price_old)
SELECT * FROM cte WHERE my_row_num > 1;

Sample output:
