I'm not really sure about that one way or the other. Our policy on which configurations are supported vis-a-vis 'make installcheck' seems to be, essentially, that if a sufficiently-prominent community member cares about it, then it ends up getting made to work, unless an even-more-prominent community member objects. That's why, for example, our regression tests pass in Czech. I can't begin to guess whether breaking installcheck against configurations with low values of max_parallel_workers or max_worker_processes will bother anybody. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
