I'd hazard a guess that there is another role which is a member of this
one.... connect to the database using psql, and then \du will give you a
list of all roles - in the output from \du, look at the column "Member of".

All of the roles have {} under "member of", so I assume that means no members?
 

HTH,

You could try:

SELECT C.relname, C.reltype
FROM pg_class C, pg_authid O
WHERE O.rolname = 'jpate'
AND C.relowner = O.oid;
