Tom Lane 28048cbaa2 Allow callers of create_foreignscan_path to specify nondefault PathTarget.
Although the default choice of rel->reltarget should typically be
sufficient for scan or join paths, it's not at all sufficient for the
purposes PathTargets were invented for; in particular not for
upper-relation Paths.  So break API compatibility by adding a PathTarget
argument to create_foreignscan_path().  To ease updating of existing
code, accept a NULL value of the argument as selecting rel->reltarget.
