Tom Lane 1b1d3d92c3 Remove ph_may_need from PlaceHolderInfo, with attendant simplifications. The planner logic that attempted to make a preliminary estimate of the ph_needed levels for PlaceHolderVars seems to be completely broken by lateral references. Fortunately, the potential join order optimization that this code supported seems to be of relatively little value in practice; so let's just get rid of it rather than trying to fix it. Getting rid of this allows fairly substantial simplifications in placeholder.c, too, so planning in such cases should be a bit faster. Issue noted while pursuing bugs reported by Jeremy Evans and Antonin Houska, though this doesn't in itself fix either of their reported cases. What this does do is prevent an Assert crash in the kind of query illustrated by the added regression test. (I'm not sure that the plan for that query is stable enough across platforms to be usable as a regression test output ... but we'll soon find out from the buildfarm.) Back-patch to 9.3. The problem case can't arise without LATERAL, so no need to touch older branches.		13 years ago
