Discussion: psql \et <trigger_name> -> edit the trigger function

We already have
\ef
\ev

The use case here is simply that it saves me from:
\d <table>
[scroll through all the fields]
[often scroll right]
select function name
\ef [paste function name]

and tab completion is much narrower

When doing conversions and reviews all of this stuff has to be reviewed.
Oftentimes, renamed, touched.

I am 100% willing to write the code, docs, etc. but would appreciate
feedback.
