Etsuro Fujita c2bb02bc2e Allow asynchronous execution in more cases. In commit `27e1f1456`, create_append_plan() only allowed the subplan created from a given subpath to be executed asynchronously when it was an async-capable ForeignPath. To extend coverage, this patch handles cases when the given subpath includes some other Path types as well that can be omitted in the plan processing, such as a ProjectionPath directly atop an async-capable ForeignPath, allowing asynchronous execution in partitioned-scan/partitioned-join queries with non-Var tlist expressions and more UNION queries.

Etsuro Fujita c2bb02bc2e Allow asynchronous execution in more cases.

In commit 27e1f1456, create_append_plan() only allowed the subplan
created from a given subpath to be executed asynchronously when it was
an async-capable ForeignPath.  To extend coverage, this patch handles
cases when the given subpath includes some other Path types as well that
can be omitted in the plan processing, such as a ProjectionPath directly
atop an async-capable ForeignPath, allowing asynchronous execution in
partitioned-scan/partitioned-join queries with non-Var tlist expressions
and more UNION queries.
