[postgis-users] PostgreSQL Linked Server on SQL Server 2005 64-bit

[Paragon Corporation]

On further inspection I see the one you are pointing at is a commercial
implementation of the PostgreSQL OLE DB Provider and  not the one packaged
with PostgreSQL source and binaries.  We haven't tried that one at all so
can't vouch for its strength compared to using ODBC over the OLEDB Provider
for ODBC.
 
A really robust solution I would suspect would be a Native SQL Server .NET
provider for PostgreSQL, but I haven't figured out how all that works to see
if the NpgSQL.NET driver can be fashioned as such.  I think native SQL
Server  for Oracle and DB2 providers exist.
 
Thanks,
Regina

I have doubt about performance and scalability of this approach. Correct me
if I'm wrong but native PostgreSQL OLE DB Provider would have done work more
efficiently (see http://www.postgresql.org/about/news.895 - version 1.2.8
supports Linked Servers).

Sorry for the cross-post here.  I think the issue of being able to connect
to PostgreSQL from a 64-bit Windows system and in particular 64-bit SQL
Server 2005 has come up a couple of times on both PostGIS and PostgreSQL
ODBC groups.  Jeff Crumbley kindly notified us that Microsoft released this
month a 64-bit OLEDB for ODBC driver which now makes connecting from a 64-it
SQL Server install via a Linked Server configuration possible.  We thank him
greatly for that and have our linked servers working now.

We have posted the steps we took to achieve this on an Intel 64-bit SQL
Server 2005 install.  So far seems to work well for us.  We hope this
information is valuable to others.
