Hi!
I faced with planner error:
ERROR: could not find RelOptInfo for given relids
A test case is in attachment, all supported versions of pgsql and HEAD are
affected.
Suppose, there is something wrong in pull_up_sublinks_qual_recurse() near
converting NOT EXISTS into join, because preventing such convertion makes query
worked. But I'm not sure.
