Hi, I have postgres 9.6 running server on centos 7, the number of wal file in pg_xlog directory is above 4000 so to save some disk space, I thought of reducing to 100. but there is no reduction in numbers. Please not that there is no replication is configured, the server is independent. What I am missing here. • max_wal_size = '3GB' • checkpoint_timeout = '15min' • checkpoint_completion_target=0.8 • log_checkpoints=on • wal_keep_segments=100 (initially it was set to 4000) Please suggest when the number of wal files will be reduced to approx 100. regards, Atul
