Late in the development of commit 2489d76c4, I (tgl) incorrectly concluded that the new function have_unsafe_outer_join_ref couldn't ever reach its inner loop. That should be the case if the inner rel's parameterization is based on just one Var, but it could be based on Vars from several relations, and then not only is the inner loop reachable but it's wrongly coded. Despite those errors, it still appears that the whole thing is redundant given previous join_is_legal checks, so let's arrange to only run it in assert-enabled builds. Diagnosis and patch by Richard Guo, per fuzz testing by Justin Pryzby. Discussion: https://postgr.es/m/20230212235823.GW1653@telsasoft.com
