From 8c7f64b0ed32b8b7d62055efc153ddd17b4a8334 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 30 Jul 2018 12:35:49 -0400 Subject: [PATCH] Fix pg_dump's failure to dump REPLICA IDENTITY for constraint indexes. pg_dump knew about printing ALTER TABLE ... REPLICA IDENTITY USING INDEX for indexes declared as indexes, but it failed to print that for indexes declared as unique or primary-key constraints. Per report from Achilleas Mantzios. This has been broken since the feature was introduced, AFAICS. Back-patch to 9.4.
