BUG #15761: ODBC: SQLForeignKeys-ResultSet-Column 'deferrablity'

The following bug has been logged on the website:

Bug reference:      15761
Logged by:          Alexander Roskamp
Email address:      alexander.roskamp@gmail.com
PostgreSQL version: 9.6.2
Operating system:   Linux
Description:

Server: Docker-Container kartoza/postgis:9.6-2.4
Client: 9.3.4 (shipped with openSUSE Leap 42.3)

The ResultSet of the SQLForeignKeys-Function shows a column "deferrablity".
Due to the Microsoft-Documentation, I am expecting the column name
"DEFERRABILITY". Please notice the missing "i".

I think the problem is hidden in Line 5856:

Is there a possibility to fix this problem?
