there'ssome sort of issue with Safe and Encode or Encode::Alias (the latter `require`s Encode in two if its methods).
Canyou replicate it? It's driving me absolutely batshit. I'm using Perl 5.10.2, Safe 2.20, and Encode 2.39. 

Also, my encoding is en_US.UTF-8. I think it matter that it's UTF-8, to judge by the
    if (GetDatabaseEncoding() == PG_UTF8)

Block in plperl.c.
