PostgreSQL Linked server question with MSSQL2K

I have to update a PostgreSQL linked server through MSSQL2K.

I first configured the connection with ODBC as follows and I can do queries
with no problem:

EXEC sp_droplinkedsr vlogin @rmtsrvname = 'PostgreSQL', @locallogin = NULL

EXEC sp_DropServer 'PostgreSQL'

EXEC sp_AddLinkedSer ver
@server = 'PostgreSQL',
@srvproduct = 'Microsoft OLE DB Provider for ODBC Driver',
@provider = 'MSDASQL',
@datasrc = 'PostgreSQL', -- a previously created and configured ODBC data
@location = 'localhost',
@catalog = 'public'

EXEC sp_AddLinkedSrv Login
@rmtsrvname = 'PostgreSQL',
@useself = 'FALSE',
@locallogin = NULL,
@rmtuser = 'postgre', -- User and password created in PostgreSQL pgAdmin
@rmtpassword = 'password'

"Customer"' ) -- ** Notice CustId column **

FYI, I SHOULD be able to use SELECT * FROM PostgreSQL...Cu stomer, but I get
this message:

Server: Msg 7313, Level 16, State 1, Line 1
Invalid schema or catalog specified for provider 'MSDASQL'.
OLE DB error trace [Non-interface error: Invalid schema or catalog
specified for the provider.].

But when I specify the schema/catalog, I get this message:

Server: Msg 7312, Level 16, State 1, Line 1
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.
OLE DB error trace [Non-interface error].

When I try to update the PostgreSQL linked server with:

''WBJ''') SET "CustName" = 'Test name'

The server returns:

Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'MSDASQL' reported an error.
[OLE/DB provider returned message: ERROR: column "custid" does not exist]
OLE DB error trace [OLE/DB Provider 'MSDASQL' IRowsetChange:: SetData
returned 0x80004005: ].

Well, custid DOES exist in the customer table and this makes no sense.

So, I tried to use - PostgreSQL OLE DB Provider:

EXEC sp_droplinkedsr vlogin @rmtsrvname = 'PostgreSQL', @locallogin = NULL

EXEC sp_DropServer 'PostgreSQL'

EXEC sp_AddLinkedSer ver
@server = 'PostgreSQL',
@srvproduct = 'PostgreSQL OLE DB Provider',
@provider = 'PostgreSQL',
@provstr = 'Password=passw ord;User ID=postgre;Loca tion=database',
@datasrc = 'localhost',
@catalog = 'public'

EXEC sp_AddLinkedSrv Login
@rmtsrvname = 'PostgreSQL',
@useself = 'FALSE',
@locallogin = NULL,
@rmtuser = 'postgre', -- User and password created in PostgreSQL pgAdmin
@rmtpassword = 'password'

The linked server is successfully created, but when I try to run a query, I
get this message:

Server: Msg 7302, Level 16, State 1, Line 2
Could not create an instance of OLE DB provider 'PostgreSQL'.
OLE DB error trace [Non-interface error: CoCreate of DSO for PostgreSQL
returned 0x80040154].

From reading Internet posts, I know that the 'PostgreSQL OLE DB Provider' is
buggy, but I need to update the PostgreSQL database in some way from SQL
Server because of the design of the application.

Can someone help getting the ODBC linked server running in a way where I can
run UPDATE? Is there just something wrong with my syntax? Can someone help
get the OLE DB provider running?

Can anyone help with why our pages are slow to load during peak-use hours? We run a database site getting 4 million hits a month which becomes painfully slow during peak hours.

Hi, Is it possible to define "linked servers" like in MS-SQL? Or - is any work going on to implement such feature?
