From af205152ef57cf54730c38342878cb6b9f8ce7a1 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Thu, 24 Nov 2022 16:07:59 +0900 Subject: [PATCH] Add the database name to the ps display of logical WAL senders Logical WAL senders display now as follows, gaining a database name: postgres: walsender USER DATABASE HOST(PORT) STATE Physical WAL senders show up the same, as of: postgres: walsender USER HOST(PORT) STATE This information was missing, hence it was not possible to know from ps if a WAL sender was a logical or a physical one, and on which database it is connected when it is logical.
