Hi Gerhard I also found the pg_log has 73 G of data .
clusternode2:/var/lib/pgsql/data # du -sh pg_log/ 73G pg_log/
Is it necessary to keep this Log files? Can i backup the logs and delete it from the original directory ? Is this logs files necessary in case any data recovery to be done ? I am database dumps every day .
you're probably logging too much. Change level of logging (log_statement to ddl for instance), and do 'pg_ctl reload'
