Hmm, in a case like this, I think we shouldn't need to detect it. The Var is perfectly parallel-safe, the problem is that we can't use a not-safe plan for the inner rel. I wonder why that's happening here... is it a problem with your patch or an existing bug? -- 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
