Languages with a "u" should be "untrusted" by PostgreSQL, because they
are free to do anything the language can do. For instance, in plperlu,
you can make socket connections, open files, and do all kinds of
dangerous things.
Languages without a "u" can be safely "trusted" by PostgreSQL, because
they are resricted to using a safe subset of the language's
functionality.
