Objects in an extension are shippable to a foreign server if the extension is part of the foreign server definition's shippable extensions list. But this was not properly considered in some cases when checking whether a join condition can be pushed to a foreign server and the join condition uses an object from a shippable extension. So the join would never be pushed down in those cases. So, the list of extensions needs to be made available in fpinfo of the relation being considered to be pushed down before any expressions are assessed for being shippable. Fix foreign_join_ok() to do that for a join relation. The code to save FDW options in fpinfo is scattered at multiple places. Bring all of that together into functions apply_server_options(), apply_table_options(), and merge_fdw_options(). David Rowley and Ashutosh Bapat, per report from David Rowley |
