I think this is what you're looking for Richard:
SELECT attname FROM pg_attribute pa, pg_class pc
WHERE pc.relname = 't1'
AND pa.attrelid = pc.relfilenode
AND pa.attisdropped IS FALSE
AND pa.attnum > 0;
Let me know if it doesn't do what you intended.

This may be a simple but can I create a query such as
select (select attname from pg_attribute where attrelid = (select relfilenode
from pg_class where relname = 't1') and attisdropped = false and attnum > 0)
from t1;
I get
ERROR: more than one row returned by a subquery used as an expression
Thanks
