Sure. just prefix the table name with the schemaname and a .
create schema abc;
alter user me set search_path='abc', 'public';
create table z1 (id int primary key);
\d z1
Table "abc.z1"
Column | Type | Modifiers
--------+---------+-----------
id | integer | not null
Indexes:
"z1_pkey" PRIMARY KEY, btree (id)
(Note the abc.z1 there)
create schema test3;
create table test3.z2 (id int primary key, z1id int references abc.z1(id));
\d test3.z2
Table "test3.z2"
Column | Type | Modifiers
--------+---------+-----------
id | integer | not null
z1id | integer |
Indexes:
"z2_pkey" PRIMARY KEY, btree (id)
Foreign-key constraints:
"z2_z1id_fkey" FOREIGN KEY (z1id) REFERENCES z1(id)
basically, schemas are just distinct name spaces.
