Hello,
The run (as user 'postgres') on the server of the cmd:
pg_basebackup -U ${DBSUSER} -Ft -z -D /data/postgresql11/backup-wal_archive-20200414-1/
produces correctly the following situtation on the server:
srap32dxr1:/data/postgresql11 # ls -ltrh backup-20200414-1
total 1.7G

The content of the dir wal_archive/ is growing and growing over the
time.
The pg_wat.tar.gz contains:
srap32dxr1:/data/postgresql11 # tar tzf backup-20200414-1/pg_wal.tar.gz
000000010000000C0000009D
i..e. the files 000000010000000C0000009B ... 000000010000000C0000009D
could be removed in wal_archive/
Correct? Or how is the long time storage of this dir?
