UPDATE pg_language SET lanpltrusted=true WHERE lanname='plpgsql'

I have:

---------------------------------------------------------------------

template1=# select * from pg_language;

lanname | lanispl | lanpltrusted | lanplcallfoid | lancompiler
----------+---------+--------------+---------------+-------------
internal | f | f | 0 | n/a
C | f | f | 0 | /bin/cc
sql | f | f | 0 | postgres
plpgsql | t | f | 16709 | PL/pgSQL
(4 rows)

---------------------------------------------------------------------

I wanna do this:

---------------------------------------------------------------------
UPDATE pg_language SET lanpltrusted=true WHERE lanname='plpgsql';
---------------------------------------------------------------------

Is this gonna break anything? That is, are there dependencies
in this table that I will break or otherwise compromise if I
perform the above sql update. Does the effect of:

'CREATE TRUSTED LANGUAGE'

differ from:

'CREATE LANGUAGE',

some way other than setting true, the 'lanpltrusted' column of
the 'plpgsql' row, of the 'pg_language' table?

I understand that my other option is to delete the language
and then add it create it
again with:

---------------------------------------------------------------------
drop language 'plpgsql';
drop function 'plpgsql_call_handler';

CREATE FUNCTION plpgsql_call_handler ()
RETURNS OPAQUE
AS '/usr/lib/postgresql/plpgsql.so'
LANGUAGE 'C';

CREATE TRUSTED LANGUAGE 'plpgsql' HANDLER plpgsql_call_handler
LANCOMPILER 'PL/pgSQL';
---------------------------------------------------------------------

Thanks.
Cheers,
