psql missing feature: show permissions for functions

Hi,


I was trying to check some permissions on functions and then I noticed
that there's no command in psql to show that information.  I've tried
using "\z", "\df" and "\df+" without success on PostgreSQL 7.4.5.

It would be an interesting addition to have that, as we do have the
commands to show permissions on tables.


Thanks for your attention,
