From de924f4bb3eb26d24c32b344ebf047f03dd1d94d Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 12 Oct 2022 10:51:11 -0400 Subject: [PATCH] Doc: improve recommended systemd unit file. Add After=network-online.target Wants=network-online.target to the suggested unit file for starting a Postgres server. This delays startup until the network interfaces have been configured; without that, any attempt to bind to a specific IP address will fail. If listen_addresses is set to "localhost" or "*", it might be possible to get away with the less restrictive "network.target", but I don't think we need to get into such detail here. Per suggestion from Pablo Federico.
