Hi All,

Is there any impact if  "#wal_keep_segments = 0 " and "checkpoint_segments = 128" postgresql.conf file. If yes,what is the imapct?

checkpoint_segments = 128 # in logfile segments, min 1, 16MB each

#checkpoint_timeout = 5min # range 30s-1h

#checkpoint_completion_target = 0.5 # checkpoint target duration, 0.0 - 1.0

#checkpoint_warning = 30s # 0 disables

#wal_keep_segments = 0 # in logfile segments, 16MB each; 0 disables

wal_level = archive # minimal, archive, or hot_standby

archive_mode = off # allows archiving to be done
