   Drew from TLUG (off the list) helped me figure this one out. I had to 
enable binmode and change my DB connect string to:

my $dbh=DBI->connect("DBI:Pg:dbname=dbname", "user", "secret",
	{
		RaiseError => 1,
		AutoCommit => 1,
		pg_enable_utf8 => 1
	}
) || die "DBI connect error: $DBI::errstr\n";
binmode STDOUT, ":utf8";

   And there ya go. :)
