Tom pointed me to this thread, since we hit it in 12.0 https://www.postgresql.org/message-id/flat/16802.1570989962%40sss.pgh.pa.us#070f6675a11dff17760b1cfccf1c038d I can't say much about the patch; there's a little typo: "The nullability of inner relation keys prevents them to" ..should say "prevent them from". In order to compile it against REL12, I tried to cherry-pick this one: 3373c715: Speed up finding EquivalenceClasses for a given set of rels But then it crashes in check-world (possibly due to misapplied hunks). -- Justin Pryzby System Administrator Telsasoft +1-952-707-8581
