Sounds pretty strange to me. What exactly do you mean by not pointing to a valid parent? Do you mean the parent_relid index is not a valid RelOptInfo? Can you point to the regression test that's doing this? -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
