Hi Mauro,
Not possible in PostgreSQL.
However, you can use dblink for creating query between multidatabase as
given below:
select empno from dblink('dbname=edb','SELECT empno from emp') as
emp(empno numeric)
union
select empno from dblink('dbname=enterprisedb','SELECT empno from emp')
as emp(empno numeric);
where edb and enterprisedb are database names
For More information about dblink, please follow the link given below:

Hi all,
is possible in PostgreSQL to create query between multidatabase like Sql Server
2005?
An example:
SELECT
db1.a.id FROM db1.a
UNION
db2.b.id FROM db2.b
Where "db1" is a database and "db2" is another database. "a" is a table in database "db1" and
"b" is a table in database "db2"
Best regards,
Mauro
