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

[Paragon Corporation]

Konstantin,
 
We'll have to take a look at that.  I always thought that the PostgreSQL OLE
DB provider was less tested and robust than the ODBC one, but I have to
admit its been a while since we have looked at it.   Last I tried it which
was awhile ago, I couldn't get it to go in a linked server configuration or
for SSIS processing.   Things have probably changed as you mention.
 
I'll have to revisit this.
 
Thanks for the suggestion.
 
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.
