Subject: Request for new column in pg_namespace

Message-ID: <CANzqJaCCF9kpfdbWbRR2xuqH_qaBgL+me13w2c-5S=_YATKh+Q@mail.gmail.com> (raw)

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;
