I'm still a consultant for a living, so I use the psql command line on a
variety of client systems a lot. And I'll tell you that 80% of the time
I use \df it's to look up the exact spelling and parameters of a
user-defined function, not a builtin. The builtins are well-documented
in the PostgreSQL docs; why would I use \df to look them up?
In other words, no, I can't tell you that this patch is well-implemented
(and for that matter I don't like the syntax of \dfS), but I can say
that the *current* behavior is annoying and time-wasting, and always has
been. It's also inconsistent with the behavior of \dt.
So I'm not arguing for this patch ... I'd reject it on messy syntax
grounds, and because I think a general \system switch is cleaner ... but
I am arguing against rejecting the idea that we want the default
behavior to show user-defined functions.
