plr installation

[Viktor Bojović]

Hi,

im trying to install PL/R into postgresql, but im unable create function as
normal user because the language is not trusted.
Is it possible to install plr as a trusted language instead of giving user
superuser rights?
The message i get is this:
ERROR: permission denied for language plr

Here are pg_laguage records:
bioinf=> SELECT * from pg_language;
lanname | lanowner | lanispl | lanpltrusted | lanplcallfoid | lanvalidator
| lanacl
----------+----------+---------+--------------+---------------+--------------+--------
internal | 10 | f | f | 0 | 2246 |
c | 10 | f | f | 0 | 2247 |
sql | 10 | f | t | 0 | 2248 |
plperl | 10 | t | t | 3709344925 | 3709344926 |
plpgsql | 10 | t | t | 3709344928 | 3709344929 |
*plr | 10 | t | f | 3313675089 | 0 |*
(6 rows)

if i try to update lanpltrusted field in that table, can that produce some
damage on database?
update pg_language set lanpltrusted=not( lanpltrusted ) where lanname='plr';

thanks in advance

No. PL/R is untrusted because R gives access to system commands and the
file system. No way around it at the moment, nor in the foreseeable future.
