Hi Team,

My env, I set postgres archive_timeout='30min' as below:

postgres=# show archive_timeout ;
archive_timeout

30min
(1 row)

postgres=# show archive_command ;
archive_command

/usr/bin/pg_probackup-12 archive-push -B /pg_backup_cfs --instance pgsql --wal-file-name=%f
(1 row)

postgres=#

pg_probackup-12 archive_timeout is the default setting 5min.
[postgres@10-176-2-190.rds-app-test.dgdev01 pgsql]$ pg_probackup-12 show-config -B /pg_backup_cfs/ --instance pgsql

but I always meet backup wait for archive problem, and lead to backup fail.
