From 25f5bd221a683ea93f4c19fdfc03924a9492984a Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Wed, 16 Nov 2022 16:00:07 +1300 Subject: [PATCH] Fix slowdown in TAP tests due to recent walreceiver change. Commit 05a7be93 changed the timing of the first reply sent by a walreceiver, which caused some TAP tests to wait in wait_for_catchup for ~10 seconds (wal_receiver_status_interval). Fix by sending an initial reply message immediately, and do the same for HS for consistency.
