wal files stay in the pg_xlog dir - Mailing list pgsql-general

To whom it may concern:

We have a 2 nodes postgres cluster, postgres server v9.3.8 and repmgr is
used to enable the cluster function. barman v1.4.1 is used to take backup of
the master postgres node.

everything seems to be working except the wal files in pg_xlog on node1
keeps accumulating.

there is a backup file everytime the backup happens under the pg_xlog
directory.

-rw------- 1 postgres postgres      327 Aug 28 02:33
000000230000000F00000075.00000028.backup

pg_xlog/archive_status shows that archive is up to date.

-rw------- 1 postgres postgres 16777216 Aug 28 15:46

drwx------ 2 postgres postgres    86016 Aug 28 15:47 archive_status
-rw------- 1 postgres postgres 16777216 Aug 28 16:00
000000230000000F0000009C

inside of archive_status the latest is 09B
-rw------- 1 postgres postgres 0 Aug 28 15:46 000000230000000F0000009B.done

it seems that wal files are not being removed after archive. i read
archive_cleanup? do i need to set it up for wal files clean up? if so how to
do that?

Thank you in advance!
