odbc_fdw is a third party extension you will need to contact other 
resources:

1) The dedicated Postgresql ODBC  list:

https://www.postgresql.org/list/pgsql-odbc/

2) The issues page for the driver maintainers:

https://github.com/CartoDB/odbc_fdw/issues

If you need immediate attention then you will need to reach out to one 
of the professional support companies listed here:

https://www.postgresql.org/support/professional_support/

When you do the above you will need to provide more information, at least:

1) Postgres version

2) SQL Server version.

3) OS version.

4) What fdw_win64_17_bin is and where you installed it from.

5) The location of your Postgres installation and ODBC installation
