The regression tests now fail on a number of tests due to a server crash:
2017-04-08 18:55:19.826 PDT  pg_regress/errors STATEMENT: select
TRAP: FailedAssertion("!(((((const Node*)(a))->type) == T_Bitmapset))", File:
"bitmapset.c", Line: 601)
2017-04-08 18:55:22.487 PDT  LOG: server process (PID 90785) was
terminated by signal 6: Abort trap
2017-04-08 18:55:22.487 PDT  DETAIL: Failed process was running:
explain (costs off)
select * from onek2 where unique2 = 11 and stringu1 = 'ATAAAA';
This is very near where the original crash reported in this thread was
crashing, probably only
different due to the extra lines of Assert that were added. Am I missing some
portion of the
fix that you are testing? I have only applied the patch that Tom included in
the previous email.
