PostgreSQL Linked Server question

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?

Hi everyone. I just finished a course on PostgreSQL and I found out that PostgreSQL doesn't provide any object relational features (as claimed in the official documentation), except table inheritance and very limited user defined types (I defined a UDT with 2 attributes and couldn't use it in a table, and the trainer said it must contain 1 attribute at most so that it can be used (as a column) in tables) So my question is whether...

Hi, Is it possible to define "linked servers" like in MS-SQL? Or - is any work going on to implement such feature? So that using 2 postgresql DB's where one is in dmz and one in production - the last one has defined the one in dmz as a "linked server" and sql's sent to the internal DB can do joins between tables in internal DB and DB in dmz?
