pgsql: When two base backups are started at the same time with pg_baseb - Mailing list pgsql-committers

When two base backups are started at the same time with pg_basebackup,
ensure that they use different checkpoints as the starting point. We use
the checkpoint redo location as a unique identifier for the base backup in
the end-of-backup record, and in the backup history file name.

Bug spotted by Fujii Masao.
