Thread: Wrong dependency in parallel regression test

Notice that the parallel regression test runs

parallel group (7 tests):  create_aggregate create_operator inherit
triggers constraints create_misc create_index

create_index creates an index on a table "onek2" which is created in
create_misc.  I just saw this fail because create_index got there first.
On the next run everything was OK.

It's interesting that no one has seen this before, so it's quite
low-probability.  I'll just mention it here for the archives.

Wow.  Has anyone tried to do an exhaustive check that the parallel
regression test schedule is OK?

I'd think that it could be done in a reasonable amount of time by
running each test of each parallel group (a) first and (b) last
among its group.
