In different schemas. For example:
create schema first;
create schema second;
create table first.atable ( id serial primary key, value text );
create table second.atable ( id serial primary key, value text );
insert into first.atable (value) values ('this is in first schema');
insert into second.atable (value) values ('this is in second schema');
select * from second.atable;
select * from atable;
ERROR (possibly)
and then there is the search path:
set search_path to second, first;
select * from atable;
Gives: value == 'this is second schema'
Hope that helps.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
