[ scratches head... ]  Works for everybody else.  I have to suppose
there's something broken about your libperl, or plperl somehow got
built wrong.  How did you build or come by your copies of perl and
postgresql?

            regards, tom lane

Yeah, this is a bug with safe 2.20 :( see
-http://rt.perl.org/rt3/Ticket/Display.html?id=72068

I would either try out this fix:
 http://github.com/timbunce/Safe/commits/master.

Or downgrade to 2.19 for now:
$ cpan
cpan> install RGARCIA/Safe-2.19.tar.gz
....

This is the issue I asked about on -hackers last month, and which I finally=
 tracked down yesterday to a bug in Safe.pm 2.20. Tim Bunce has since fixed=
 it. Report here:

    http://rt.perl.org/rt3/Public/Bug/Display.html?id=3D72068

In the short run, you can downgrade to Safe.pm 2.19 and the problem will go=
 away. Or just use PL/Perlu, which doesn't rely on Safe.pm.

Best,

David
