From 2c84ea6cf994f5853de0f03600aa5df8156cf9f4 Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Tue, 9 Jul 2019 17:16:36 -0400 Subject: Propagate trigger arguments to partitions We were creating the cloned triggers with an empty list of arguments, losing the ones that had been specified by the user when creating the trigger in the partitioned table. Repair. This was forgotten in commit 86f575948c77.
