That's one way of looking at it. :)

You can do that with declarative partitions:
create table foo (a int) partition by list (a);
create schema foo_parts;
create table foo_parts.foo1 partition of foo for values in (1);
create table foo_parts.foo2 partition of foo for values in (2);
\d
List of relations
Schema | Name | Type | Owner
--------+------+-------+-------
public | foo | table | amit
(1 row)
set search_path to foo_parts;
\d
List of relations
Schema | Name | Type | Owner
-----------+------+-------+-------
foo_parts | foo1 | table | amit
foo_parts | foo2 | table | amit
(2 rows)
Thanks,
Amit
