I can agree that it's reasonable for the default behavior with no
arguments (no pattern) to be to show only user-defined objects.
Otherwise you're going to get quite a long list, which doesn't
seem particularly useful --- and if you really want that, you can
say '*.*' so there's no loss of functionality if we change it.
However, if we don't have that restriction when a pattern is given,
I wonder whether we need the 'S' modifier at all. If you really
want to see only system objects, there's 'pg_catalog.*', but this
doesn't seem like a case that's so common that it needs a command
modifier letter.
So my proposal at the moment is to get rid of 'S', have the behavior
with a pattern be the same as it was before, and only change the
behavior with no pattern.
