Perhaps this link may help:
https://www.mssqltips.com/sqlservertip/3663/sql-server-and-postgresql-foreign-data-wrapper-configuration--part-3/

The only caveat I see offhand is the use of the 'sa' account, but I can't vouch for that being a required mapping.

Hi John,

Thanks, but I already saw that link. The problem is to installing the tds_fwd extension on postgres. And I don't know how to (never tried) compile it...

What comes with postgres by default is the postgres fdw, that allow to link 2 different postgres servers, but in this case that doesn't help me.

Sorry Ivo, my bad - I managed to gloss over the salient point for your issue in this link - you're on Windows, his Postgres was on Linux!

Compiling an extension on Windows, last time I tried many moons ago was unfortunately not successful, which involved compiling the whole pg source tree via MinGW.

Hazarding a thought - although it's discontinued, it might be worth checking out Windows Subsystem for UNIX-based Applications (SUA):

https://en.wikipedia.org/wiki/Windows_Services_for_UNIX

But I suspect anything you managed to compile with that would still be incompatible with your pg instance...

Beyond that, perhaps the gurus here have some sage advice...
