I believe that's a hangover from back when each large object was its own
relation. [digs in archives...] OK, that's dead code since 7.1, and it
was wrong before that ... the special relation names were xin* ...
In 7.3, suppressing relnames starting with 'pg_' isn't really quite the
kosher way to hide system tables, either. It works but it might
suppress legitimate user tables --- there's not a prohibition against
user tables named 'pg_*' anymore. The best way moving forward will be
to ignore tables that are in system schemas.
