Hi, all.
Running PostgreSQL 9.1.8 on Xubuntu 12.04, installed from the repos.
From the shell, I have executed:
createlang plperl db_name;
createlang plperlu db_name;
As the superuser running `psql`, I have executed:
GRANT ALL ON LANGUAGE plperl TO account_name;
GRANT ALL ON LANGUAGE plperlu TO account_name;
The `pg_language` table reveals:
select lanname,lanpltrusted from pg_language where lanname like
'plperl%';
"plperl";t
"plperlu";t
When I create the following function:
CREATE OR REPLACE FUNCTION get_hostname()
RETURNS text AS
$BODY$
use Sys::Hostname;
return hostname;
$BODY$
LANGUAGE plperlu IMMUTABLE
COST 1;
ALTER FUNCTION get_hostname()
OWNER TO account_name;
I receive the following error:
ERROR: Unable to load Sys/Hostname.pm into plperl at line 2.
BEGIN failed--compilation aborted at line 2.
CONTEXT: compilation of PL/Perl function "get_hostname"
Yet the following works:
CREATE OR REPLACE FUNCTION get_hostname()
RETURNS text AS
$BODY$
return '127.0.0.1';
$BODY$
LANGUAGE plperlu IMMUTABLE
COST 1;
ALTER FUNCTION get_hostname()
OWNER TO account_name;
The following Perl script works as expected from the shell:
use Sys::Hostname;
print hostname;
I tried to run the function as an anonymous block:
DO $$
use Sys::Hostname;
print hostname;
$$ LANGUAGE plperlu;
This returned the same error as before, with this additional information:
ERROR: Unable to load Sys/Hostname.pm into plperl at line 3.
BEGIN failed--compilation aborted at line 3.
SQL state: 42601
