Hi

Currently, when I want to query all "userland" tables, I write something like:
select ...
from pg_class cl, pg_namespace nsp
where cl.relnamespace = nsp.oid
  and nsp.nspname not like 'pg_%
  and nsp.nspname != 'information_schema';

A new boolean column named "indissystem" that's true only for system relations would make many maintenance queries cleaner, since they'd look like:
select ...
from pg_class cl, pg_namespace nsp
where cl.relnamespace = nsp.oid
  and nsp.indissystem = false;


oid of all system objects is less then 0x4000

Regards

Pavel
