From 56ca885db70845775e49a2e78971946d17620a24 Mon Sep 17 00:00:00 2001 From: Krzysztof Opasiak Date: Tue, 4 Feb 2020 16:07:20 +0100 Subject: [COMMON] Share deployment configuration in Postgres When I did diff between deployment-primary and deployment-replica it turned out that this is pretty much the same file apart from primary and replica words. To avoid making the same changes in both files, let's just introduce a template that can be included with parameter.
