I agree with Andreas' suggestion that the help string be "list
procedural languages", even though the \dLS output looks something
like this:
List of languagesProcedural Language | Owner | Trusted
---------------------+-------+---------c | josh | finternal | josh | fplpgsql
| josh | tsql | josh | t
(4 rows)
which, as Magnus points out, includes non-procedural languages (SQL).
I think that "list languages" could be confusing to newcomers -- the
very people who might be reading through the help output of psql for
the first time -- who might suppose that "languages" has something to
do with the character sets supported by PostgreSQL, and might not even
be aware that a variety of procedural languages can be used inside the
database.
