As you guessed, it's trying to do load the utf8 pragma, and failing
as 'require' (and 'use') are not allowed by default: plperl uses the
Safe module to disallow things like 'require Module;'. Unfortunately, the
only way around it on your end is to use plperlu - something I recommend
anyway (for other reasons).

Yes, we might want to consider making utf8 come pre-loaded for plperl. There
is no direct or easy way to do it (we don't have finer-grained control than
the 'require' opcode), but we could probably dial back restrictions,
'use' it, and then reset the Safe container to its defaults. Not sure what
other problems that may cause, however. CCing to hackers for discussion
there.
