Doesn't compile against PostgreSQL 9.5rc1 about pgsql-ogr-fdw

I submitted a pull request #46 . Guess I didn't do it right so it shows automagically here.

I've got a warning issue to fix. With my new code while it compiles and does work, I get this warning.

ogr_fdw.c: In function 'ogrGetForeignPaths':
ogr_fdw.c:536:6: warning: passing argument 8 of 'create_foreignscan_path' from incompatible pointer type [enabled by default]
      )
      ^
In file included from ogr_fdw.h:41:0,
                 from ogr_fdw.c:29:

I'll update my pull request in a bit to get rid of that warning.
