join_clause_is_movable_into() is approximate, in the sense that it might sometimes return "false" when actually it would be valid to push the given join clause down to the specified level. This is okay ... but there was an Assert in get_joinrel_parampathinfo() that's only safe if the answers are always exact. Comment out the Assert, and add a bunch of commentary to clarify what's going on. Per fuzz testing by Andreas Seltenreich. The added regression test is a pretty silly query, but it's based on his crasher example. Back-patch to 9.2 where the faulty logic was introduced.
