Oh, scratch that: the issue exists in 9.6, it's just that the particular test query you're using here does not generate a parallelized plan in 9.6, as shown by "explain". With a different query that does get parallelized, 9.6 fails too: regression=# select sum(ten) from tenk1; ERROR: role "testuser1" does not exist CONTEXT: parallel worker Still, I think it's reasonable to characterize this as "must fix for v10". regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
