Just curious:
create table a (x int4 primary key); create table a1 () inherits (a);
[...]
delete from a where x = 1000;
I take it that this is equivalent to:
delete from only a where x = 1000; delete from only a1 where x = 1000;
In particular, for performance reasons I should try to limit the
delete to a1 wherever possible?
Also, it looks like a1 doesn't inherit the primary key index. Is that
intentional or a bug?
Finally, is it possible to specify that x values be unique across
both a *and* a1, without triggers?
