If I run the regression tests with force_parallel_mode=on prior to the parallel hash join patch, they pass. If I run them now, they fail inside the parallel hash join tests here: create table wide as select generate_series(1, 2) as id, rpad('', 320000, 'x') as t; I'm guessing that test case would have failed before, too, but we didn't have it. I'll analyze this further in a bit. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
