The situation is as follows: after turning on "archive_mode", binaries began to pour into pg_xlog, they are created even at the moment when there are no calls to the database and soon the disk space (virtual, I'm running in possibilities) ends.
Question: how to enable rewriting of binlogs? I read that it is possible, but I did not meet the description of the setting.
Overwrite activated with "archive_command"?
Or is it configured by standard OS tools (in my case, CentOS 5.4), like logrotate?
Yes, moving to the latest version of the DBMS is not possible due to corporate restrictions.
