Now, it's just a suggestion as I've not used arrays before but have you tried
something like:

SELECT u.usename FROM pg_user u WHERE EXISTS (SELECT 1 FROM pg_group g WHERE
g.grolist *= u.usesysid);

You should look up arrays in the documentation since I see from there that the
*= operator is probably an extension you need to install.
