If anyone else is having issues using tds_fdw with Microsoft Azure,
the latest commit adds a foreign server-level "database" option which
fixes the dbuse() issue with Azure. See the GitHub issue for details:
https://github.com/GeoffMontee/tds_fdw/issues/23#issuecomment-109655082
I'll probably package up a tds_fdw 1.0.2 release relatively soon.
