Hi.
Is there any way to take use of indexes on foreign tables?
Currently (at least with tds_fdw, that I was testing) the planner just
does a dumb full sequential scan in all cases.
That is
SELECT drink FROM foreignbar;
-- takes as much time as
SELECT drink FROM foreignbar where drink_key = 3210;
It is possible but implementation is the responsibility of the FDW middleware authors.
Since "tds_fdw" is not core this would not be the correct forum.
