Restructure code that is responsible for ensuring that clauseless joins are considered when it is necessary to do so because of a join-order restriction (that is, an outer-join or IN-subselect construct). The former coding was a bit ad-hoc and inconsistent, and it missed some cases, as exposed by Mario Weilguni's recent bug report. His specific problem was that an IN could be turned into a "clauseless" join due to constant-propagation removing the IN's joinclause, and if the IN's subselect involved more than one relation and there was more than one such IN linking to the same upper relation, then the only valid join orders involve "bushy" plans but we would fail to consider the specific paths needed to get there. (See the example case added to the join regression test.) On examining the code I wonder if there weren't some other problem cases too; in particular it seems that GEQO was defending against a different set of corner cases than the main planner was. There was also an efficiency problem, in that when we did realize we needed a clauseless join because of an IN, we'd consider clauseless joins against every other relation whether this was sensible or not. It seems a better design is to use the outer-join and in-clause lists as a backup heuristic, just as the rule of joining only where there are joinclauses is a heuristic: we'll join two relations if they have a usable joinclause *or* this might be necessary to satisfy an outer-join or IN-clause join order restriction. I refactored the code to have just one place considering this instead of three, and made sure that it covered all the cases that any of them had been considering. Backpatch as far as 8.1 (which has only the IN-clause form of the disease). By rights 8.0 and 7.4 should have the bug too, but they accidentally fail to fail, because the joininfo structure used in those releases preserves some memory of there having once been a joinclause between the inner and outer sides of an IN, and so it leads the code in the right direction anyway. I'll be conservative and not touch them.

Rewrite make_outerjoininfo's construction of min_lefthand and min_righthand sets for outer joins, in the light of bug #3588 and additional thought and experimentation. The original methodology was fatally flawed for nests of more than two outer joins: it got the relationships between adjacent joins right, but didn't always come to the right conclusions about whether a join could be interchanged with one two or more levels below it. This was largely caused by a mistaken idea that we should use the min_lefthand + min_righthand sets of a sub-join as the minimum left or right input set of an upper join when we conclude that the sub-join can't commute with the upper one. If there's a still-lower join that the sub-join *can* commute with, this method led us to think that that one could commute with the topmost join; which it can't. Another problem (not directly connected to bug #3588) was that make_outerjoininfo's processing-order-dependent method for enforcing outer join identity #3 didn't work right: if we decided that join A could safely commute with lower join B, we dropped all information about sub-joins under B that join A could perhaps not safely commute with, because we removed B's entire min_righthand from A's. To fix, make an explicit computation of all inner join combinations that occur below an outer join, and add to that the full syntactic relsets of any lower outer joins that we determine it can't commute with. This method gives much more direct enforcement of the outer join rearrangement identities, and it turns out not to cost a lot of additional bookkeeping. Thanks to Richard Harris for the bug report and test case.
