Hi,

I am getting a server crash on PG-HEAD with below test case.

SET parallel_setup_cost=0;
SET parallel_tuple_cost=0;
create or replace function foobar() returns setof text as
$$ select 'foo'::varchar union all select 'bar'::varchar ; $$
language sql stable;

postgres=# select foobar();
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

--logfile
2018-02-26 22:15:52.908 IST [61738] LOG: database system is ready to
accept connections
TRAP: FailedAssertion("!(whichplan >= 0 && whichplan <= node->as_nplans)",
File: "nodeAppend.c", Line: 365)
2018-02-26 22:17:50.441 IST [61738] LOG: server process (PID 61748) was
terminated by signal 6: Aborted
2018-02-26 22:17:50.441 IST [61738] DETAIL: Failed process was running:
select foobar();

Thanks Robert for fix and commit. I have reverified commit, this is working
fine now.
