Обсуждение: [COMMITTERS] pgsql: Make walsender always initialize the buffers.
Make walsender always initialize the buffers. Walsender uses the local buffers for each outgoing and incoming message. Previously when creating replication slot, walsender forgot to initialize one of them and which can cause the segmentation fault error. To fix this issue, this commit changes walsender so that it always initialize them before it executes the requested replication command. Back-patch to 9.4 where replication slot was introduced. Problem report and initial patch by Stas Kelvich, modified by me.

Doesn't look like you actually pushed the back-patch? I only see
this in HEAD.
