From 46d73e0d65eef19e25bb0d31f1e5c23ff40a3444 Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Wed, 13 Apr 2016 04:36:29 +0900 Subject: [PATCH] Remove unused function GetOldestWALSendPointer from walsender code. That unused function was introduced as a sample because synchronous replication or replication monitoring tools might need it in the future. Recently commit 989be08 added the function SyncRepGetOldestSyncRecPtr which provides almost the same functionality for multiple synchronous standbys feature. So it's time to remove that unused sample function. This commit does that. --- src/backend/replication/walsender.c | 41 ----------------------------- 1 file changed, 41 deletions(-) diff --git a/src/backend/replication/walsender.c b/src/backend/replication/walsender.c index e4a0119c5e3..81d3d285c90 100644 --- a/src/backend/replication/walsender.c +++ b/src/backend/replication/walsender.c @@ -2938,44 +2938,3 @@ WalSndKeepaliveIfNecessary(TimestampTz now) WalSndShutdown(); } } - -/* - * This isn't currently used for anything.
