Hi Andreas,

Yes I'm facing problem because of this huge WAL(archive log) generation. As
it is seriously consuming a lot of disk space almost close to 50GB per day
even if the DML's don't have that impact in this WAL generation.

Previously the archive_log size is nearly 2 to 3 GB a day. Now with the same
set of DML's how is it being generated to 50GB is my burning doubt.

Will so many wals continue to be produced?

I just wanted to know how to stabilize this issue, as checking and deleting
the archive logs on hourly basis is not a good idea.

Don't delete wal's!

Finally, I'm looking how to reduce this back to normal. Thanks in Advance.

have you set archive_mode to on and defined an archive_command? Wal-files will be reused after 2 checkpoints.
Is there something in the logs?


Regards, Andreas
