No, the "system catalog modification" restriction only applies to DDL
on the system catalogs --- for instance, adding/removing a column, which
our C code couldn't cope with. You're free to change their contents by
hand if you're a superuser. (And if you break something that way, you
get to keep both pieces. But sometimes it's necessary.)
