I had the very same problem, and after checking postgres log file, found the following warning every 5 minutes: archive_cleanup_command "pg_archivecleanup /srv/postgresql/wals/ %r": return code 32512 wich means the pg_archivecleanup script was not found. The solution: edit the file /var/lib/postgresql/9.1/main/recovery.conf and make sure it is set like this: archive_cleanup_command = '/usr/lib/postgresql/9.1/bin/pg_archivecleanup /srv/postgresql/wals/ %r' (be careful: I keep my wal files in a special dir "/srv/postgresql/wals/" yours will be a different location) in my case, after 5 minutes, my 140 GB wal dir changed to just 2 files, being one of them a .backup file. Before that, I did not had a .backup file at all, so I could not make use of wal cleanup procedures. -- View this message in context: http://postgresql.1045698.n5.nabble.com/HOT-Standby-slave-does-not-appear-to-be-removing-wal-files-tp5747774p5784441.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
