plperlをWindows上のPostgres9.1で動作させることができませんでした。
同じ問題がここで説明されていますが、これまでのところ解決策はありません:http: //postgresql.1045698.n5.nabble.com/BUG-6204-Using-plperl-functions-generate-crash-td4802111.html

ここからWindows用のPerl5.1432ビットをインストールします:http: //downloads.activestate.com/ActivePerl/releases/5.14.2.1402/ActivePerl-5.14.2.1402-MSWin32-x86-295342.msi
システムパス変数にPerlを追加します。EnterpriseDBからWindows用のPostgres9.1.232ビットをインストールしますwww.enterprisedb.com/products/pgdownload.do#windows
次に、テストDBを作成し、それにperlを追加して、関数を作成してみます。
postgres=# create database plperl_test;
CREATE DATABASE
postgres=# \c plperl_test
WARNING: Console code page (437) differs from Windows code page (1252)
8-bit characters might not work correctly. See psql reference
page "Notes for Windows users" for details.
You are now connected to database "plperl_test" as user "postgres".
plperl_test=# create language plperl;
CREATE LANGUAGE
plperl_test=# create function perl_test() returns void as
plperl_test-# $$
plperl_test$# $$
plperl_test-# language plperl;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
これにより、Postgresサーバープロセスがシャットダウンしたことに注意してください。うわぁ!
Postgresのログファイルを見ると、これが見つかります...
