t and f is just how psql prints booleans, it shouldn't be important. Also, you can simplify your query as follows:

SELECT status = 'active' AS status FROM table;

If you really want to get text for the column status, do the following:

SELECT (status = 'active')::text AS status FROM table;

If you want to get a number instead (0 for false, 1 for true), do this:

SELECT (status = 'active')::integer AS status FROM table;
