Thread: pgsql: Fix TRUNCATE .. CASCADE on partitions
Fix TRUNCATE .. CASCADE on partitions When running TRUNCATE CASCADE on a child of a partitioned table referenced by another partitioned table, the truncate was not applied to partitions of the referencing table; this could leave rows violating the constraint in the referencing partitioned table. Repair by walking the pg_constraint chain all the way up to the topmost referencing table. Note: any partitioned tables containing FKs that reference other partitioned tables should be checked for possible violating rows, if TRUNCATE has occurred in partitions of the referenced table.
