Ah yes, so basically I can implement the JDBC-alike getTablePrivileges
as something like:

 SELECT (...), tables.table_name, pr.rolname AS grantee,
        has_table_privilege(pr.oid, tables.table_schema, + '.' + tables.table_name, privilege.name), (...)
 FROM information_schema.tables, pg_catalog.pg_roles pr,
      VALUES ('SELECT', 'UPDATE', ...) AS privilege

I'd be missing a sensible value for the grantor column, but at least
it would be complete and robust for the rest of the information.

Thanks for the pointer.
