The denizens of #postgresql think that there's some sort of issue with Safe and Encode or Encode::Alias (the latter `require`s Encode in two if its methods). Can you replicate it? It's driving me absolutely batshit. I'm using Perl 5.10.2, Safe 2.20, and Encode 2.39.

I cannot reproduce this. I tested with perl 5.10.1 which is the latest

8.4.2 UTF8 database, and with the same Safe and Encode module versions
