Thanks for committing the patch!

With this change, ON_ERROR = 'set_null' can now be used with foreign tables
backed by file_fdw. However, unlike ON_ERROR = 'ignore', there is currently
no regression test covering this behavior in file_fdw.

How about adding a regression test to ensure that file_fdw works correctly
with ON_ERROR = 'set_null', and to improve test coverage? Patch attached.
