I can feel your pain...
The LIKE operators and its wildcard characters are a misfeature of SQL
itself. Fortunately for us PostgreSQL has regular expressions as an
extension to SQL -- look
http://www.postgresql.org/users-lounge/docs/7.0/user/operators2123.htm.
I would do ~ '.*[aáã].*' or something like it. For documentation, try
man 5 regexp or at Emacs man regexp(5).
