Etsuro Fujita edbcbe277d postgres_fdw: Fix cost estimation for aggregate pushdown. ... In commit 7012b132d0, which added support for aggregate pushdown in postgres_fdw, the expense of evaluating the final scan/join target computed by make_group_input_target() was not accounted for at all in costing aggregate pushdown paths with local statistics. The right fix for this would be to have a separate upper stage to adjust the final scan/join relation (see comments for apply_scanjoin_target_to_paths()); but for now, fix by adding the tlist eval cost when costing aggregate pushdown paths with local statistics. Apply this to HEAD only to avoid destabilizing existing plan choices.
