I managed to link PostgreSQL to MSSQL as a linked server but:

select * from [TEST].[test].[public].[users] <<<TEST - name of linked server
in MSSQL , test - Postgres db name, public - schema name, users - table
Returns:
Server: Msg 7312, Level 16, State 1, Line 7
Invalid use of schema and/or catalog for OLE DB provider 'MSDASQL'. A
four-part name was supplied, but the provider does not expose the necessary
interfaces to use a catalog and/or schema.

Works only via OPENQUERY:

SELECT * FROM OPENQUERY (TEST, 'select * from users');


Does anybody know how to query Postgres WITHOUT OPENQUERY.

I found in groups that:

" According to the documentation, SQL-Server supports any Win32 ODBC
  driver ... which would include PostgresODBC.  However, in practice,
  only Microsoft-supplied drivers actually work; ODBC drivers for
  Postgres and MySQL mysteriously do not function with SQL-Server (even
  though they do work with MS Access).
 I think this is incompetence on Microsoft's part rather than malice;
  all of this works through DTS, a utility which is responsible for over
  300 Knowledge Base issues.
 Note:  I have not tried any of this with SQL Server 2000, just 7.0 sp3. "


Thank you,


Igor
