The system is prepared to delete the files it no longer needs automatically. If you have WAL files piling up for no apparent reason, the most likely explanation is that the server is misconfigured, for example due to a failing archive_command, or to a high "keep" setting for WAL files (which is used in some replication scenarios). In those cases, the real solution is to fix that problem, not delete files yourself. > On Sat, Nov 23, 2013 at 1:48 AM, Kevin Grittner <kgrittn@xxxxxxxxx> wrote: > > > Pankaj <pankaj.mimit@xxxxxxxxx> wrote: > > > > > now go to pg_xlog folder you can can see a pattern in file names of logs. > > > Just remove the file other then current time stamp.
