Обсуждение: pgsql: Remove pg_constraint.conincluding
Remove pg_constraint.conincluding This column was added in commit 8224de4f42cc ("Indexes with INCLUDE columns and their support in B-tree") to ease writing the ruleutils.c supporting code for that feature, but it turns out to be unnecessary -- we can do the same thing with just one more syscache lookup. Even the documentation for the new column being removed in this commit is awkward.
