IMPORT FOREIGN SCHEMA return create foreign table commands are those further filtered in LIMIT and EXCEPT cases?

I've implemented IMPORT FOREIGN SCHEMA support for an fdw called ogr_fdw
against the PostgreSQL 9.5RC1 code base.

Code is here:  https://github.com/robe2/pgsql-ogr-fdw

It works great except in the Case of LIMIT TO  clause  (and possible EXCEPT
though I have to retest EXCEPT to see if there is a case it doesn't work).  
In LIMIT case sometimes works and it sometimes doesn't and when it doesn't
no foreign tables are created.

Key bit starts here:
https://github.com/robe2/pgsql-ogr-fdw/blob/master/ogr_fdw.c#L1389

When it doesn't work, no foreign tables are created, however when I inspect
the out list coming from the function, I see the create foreign table
statements 
And the right number as well but for some reason they never get executed.

I thought perhaps that I have a memory leak somewhere, but then I discovered
that if I take out my logic for LIMIT  and EXCEPT handling,
It still doesn't work.  In the sense that I have a ton of create foreign
table statements but none of them ever get run.

-- ogr_all is a catchall schema just to say - don't bother checking schema.

So I'm guessing there is some other filtering going on that I'm not aware
of.

Here is basic logic I have to exercise this behavior.
I should note: the two laundering options I have in place are used to
preserve or not preserve the table name and column names
When not specified, the import tries to change the table and column names so
that they don't require quoting when used in SQL.

DROP SERVER IF EXISTS northwind  CASCADE;

CREATE SERVER northwind FOREIGN DATA WRAPPER ogr_fdw OPTIONS (   datasource 'C:/fdw_data/northwind.mdb',   format
'ODBC');
 

CREATE SCHEMA IF NOT EXISTS northwind;

-- doesn't work - no tables created, but I see the two create table
statements coming out of my import function
IMPORT FOREIGN SCHEMA ogr_all    LIMIT TO("Orders", "Products")      FROM SERVER northwind INTO northwind
OPTIONS(launder_table_names 'false', launder_column_names 'false');

-- works and I get the 2 tables created
IMPORT FOREIGN SCHEMA ogr_all    LIMIT TO("Orders", "Products")      FROM SERVER northwind INTO northwind;


If I use the EXCEPT clause, it works in both these cases and produces 24
tables (with these two missing) as expected.

I tried exercising the same kind of issue with the postgres_fdw wrapper, but
was not successful replicating the issue with that one.
