Detaching a partition from a partitioned table that's constrained by foreign keys requires additional action triggers on the referenced side; otherwise, DELETE/UPDATE actions there fail to notice rows in the table that was partition, and so are incorrectly allowed through. With this commit, those triggers are now created. Conversely, when a table that has a foreign key is attached as a partition to a table that also has the same foreign key, those action triggers are no longer needed, so we remove them. Add a minimal test case verifying (part of) this. Authors: Amit Langote, Álvaro Herrera Discussion: https://postgr.es/m/f2b8ead5-4131-d5a8-8016-2ea0a31250af@lab.ntt.co.jp |
