The information schema only exposes privileges defined in the SQL
standard on objects defined in the SQL standard. So psql or any tool
that wants to provide information on PostgreSQL-specific features can't
use that. But perhaps the JDBC interfaces only expose certain standard
information anyway, so it could be useful. Depends on the details,
though.
