commit    424d7a9b277c0da5ec638bf6344cda899a2e544a
Author:   Fujii Masao <fujii@postgresql.org>
Date:     Thu Jan 14 05:37:01 2021 +0000
First released in: 14.0, 13.2

    Stabilize timeline switch regression test.
    
    Commit fef5b47f6b added the regression test to check whether a standby is
    able to follow a primary on a newer timeline when WAL archiving is enabled.
    But the buildfarm member florican reported that this test failed because
    the requested WAL segment was removed and replication failed. This is a
    timing issue. Since neither replication slot is used nor wal_keep_size is set
    in the test, checkpoint could remove the WAL segment that's still necessary
    for replication.
    
    This commit stabilizes the test by setting wal_keep_size.
    
    Back-patch to v13 where the regression test that this commit stabilizes
    was added.
