Help with create view

I am creating a view for the table:
bellus=# select * from host_application_definition;
id | type_value | connection_value | group_value | application_value | host
----+------------+------------------+-------------+-------------------+----


From the table meta_host_types;

id | value | types | name
----+-------+-----------+--------
1 | agm | host-type | Rencid

I would like to seperate value into type_value and connection_value, because it holds both values.

Any tip?

bellus=# \d host_application_definition;
Table "public.host_application_definition"
Column | Type | Modifiers
-------------------+---------+--------------------------------------------------------------------------
id | integer | not null default nextval('host_application_definition_id_seq'::regc lass)
type_value | integer |
connection_value | integer |
group_value | integer |
application_value | integer |
host | integer |
Indexes:
"host_application_definition_pkey" PRIMARY KEY, btree (id)
Foreign-key constraints:
"host_application_definition_application_value_fke y" FOREIGN KEY (application_value) REFERENCES appsmarteye(id)
"host_application_definition_connection_value_fkey " FOREIGN KEY (connection_value) REFERENCES meta_host_types(id)
"host_application_definition_group_value_fkey" FOREIGN KEY (group_value) REFERENCES meta_host_grouptypes(id)
"host_application_definition_host_fkey" FOREIGN KEY (host) REFERENCES master_hosts(id)
"host_application_definition_type_value_fkey" FOREIGN KEY (type_value) REFERENCES meta_host_types(id)



\d meta_host_types;
Table "public.meta_host_types"
Column | Type | Modifiers
-------------+---------+---------------------------------------------------------------------
id | integer | not null default nextval('meta_types_application_id_seq'::regclass)
application | integer |
value | text |
comments | text |
types | text |
Indexes:
"meta_types_application_pkey" PRIMARY KEY, btree (id)
"meta_host_types_id_key" UNIQUE, btree (id)
"meta_host_types_value_key" UNIQUE, btree (value, application)
"meta_host_types_value_key1" UNIQUE, btree (value)
Foreign-key constraints:
"meta_types_application_application_fkey" FOREIGN KEY (application) REFERENCES appsmarteye(id)

how does it hold both values???

How is it broken into multiple values?

(BTW. In order to properly normalize the table, a field should only hold one meaning, not two or more... So, to "fix" the database, you should split the field into two, and concatenate when needed)
