Short Description
plperl vs. plperlu

Long Description
Hi,

FYI, in 7.3.2, we are unable to create two languages viz, plperl and plperlu since he is trying to create the function(plperl_call_handler) and the language everytime. Infact it is not documented anywhere in the release. Someone correct me, if i am wrong. FYI, i have included the output of createlang command.

regards,
bhuvaneswaran

Sample Code
$ createlang -e -L /usr/lib/postgresql/ -d test_pg 'plperl';
SELECT oid FROM pg_language WHERE lanname = 'plperl';
SELECT oid FROM pg_proc WHERE proname = 'plperl_call_handler' AND prorettype = 0 AND pronargs = 0;
SET autocommit TO 'on';CREATE FUNCTION "plperl_call_handler" () RETURNS LANGUAGE_HANDLER AS '/usr/lib/postgresql//plperl' LANGUAGE C;
SET autocommit TO 'on';CREATE TRUSTED LANGUAGE "plperl" HANDLER "plperl_call_handler";
$ createlang -e -L /usr/lib/postgresql/ -d test_pg 'plperlu';
SELECT oid FROM pg_language WHERE lanname = 'plperlu';
SELECT oid FROM pg_proc WHERE proname = 'plperl_call_handler' AND prorettype = 0 AND pronargs = 0;
SET autocommit TO 'on';CREATE FUNCTION "plperl_call_handler" () RETURNS LANGUAGE_HANDLER AS '/usr/lib/postgresql//plperl' LANGUAGE C;
ERROR: function plperl_call_handler already exists with same argument types
createlang: language installation failed
