[PATCH] Psql List Languages

Hi,,

My job, I maintainer some postgres server for clients. We have
many PL/(Java, Perl, Ruby, Python, R) and to more easy
administration, I worked new little psql attribute to list languages
com shorcurt/function \dL.

postgres(at)darkside:/media/disk/devel/pg$ bin/psql -U postgres test
psql (8.4devel)
Type "help" for help.

test=# \dL
List of languages
Name | Owner | Procedural Language | Trusted | Call

c | postgres | No | Unstrusted |
| fmgr_c_validator
internal | postgres | No | Unstrusted |
| fmgr_internal_validator
plperl | postgres | Yes | Trusted |
plperl_call_handler | plperl_validator
sql | postgres | No | Trusted |
| fmgr_sql_validator
(4 rows)

test=#

I know that this moment is inappropriate to submit patch, with the
discussions about features for 8.4. But, if can added for commitfest
to 8.5 version. I'm appreciate.
