Обсуждение: pgsql: Fix instability in regression test for Parallel Hash Full Join

Fix instability in regression test for Parallel Hash Full Join

As reported by buildfarm member conchuela, one of the regression tests
added by 558c9d7 is having some ordering issues.  This commit adds an
ORDER BY clause to make the output more stable for the problematic
query.

Fix suggested by Tom Lane.  The plan of the query updated still uses a
parallel hash full join.
