If you are up to recompiling postgres, you might try this patch. Its
untested, but the basic idea is to always allow require 'utf8.pm' to
work in plperl. Near as I can tell utf8.pm is a strange package, when
we look to see if we already have it loaded it, we can't find it for
example. Which would explain why plperl.on_init = ' use utf8;' does
not work for you. I don't have the time to dig through a bunch of perl
versions to find out whats going on with utf8.pm.
I suspect this will make it fail on loading a different module (my gut
says utf8 is going to want to load unicore stuff once its loaded) but
it would be interesting to see nonetheless.
