The real solution here is that this patch can't throw an error if it's unable to obtain the desired number of background workers. It needs to be able to smoothly degrade to a smaller number of background workers, or none at all. I think a lot of this work will fall out quite naturally if this patch is reworked to use the parallel mode/parallel context stuff, the latest version of which includes an example of how to set up a parallel scan in such a manner that it can run with any number of workers. -- 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
