Hm, I didn't realize that. I thought the reason \df was special was that users
often need to refer to "system" functions. Whereas they never need to refer to
system tables or system sequences etc unless they know that's what they're
looking for.
However, now that I look at the list of \d commands that argument kind of
falls flat. Users also need to find "system" operators, data types, etc.
And I think the same logic as \df applies for those other things too. \dt
pg_class should "just work". And if you create a macaddr data type it doesn't
seem like too much of an imposition to play it safe and have \dT macaddr show
the user that there are now two matching data types.
So I guess I should just play along and pretend that's what I meant all along
:)
