postgres_fdw : disable extended queries

[Nicolas Paris <niparisco@xxxxxxxxx>]

Hello,

I have a 9.6 pg instance, and I am trying to link a foreign postgresql database that do not accept extended queries. (only simple queries https://www.postgresql.org/docs/current/static/protocol.html )

When I run a query against the foreign pg instance thought postres_fdw, it looks like it sends a transaction containing

DECLARE c1 CURSOR FOR
SELECT customer_id FROM foodmart.customer

-> is there a way to run a simple query with postgres_fdw such:

SELECT customer_id FROM foodmart.customer

Thanks,
