Is this a standalone server? What is the value of archive_timeout?
It is generally safe to delete WAL files older than a day or two. More specifically, all WAL files older than the latest base backup are safe to selete. A simple bash script will do in this case.
We are running PostgreSQL 9.1 with WAL. I am noticing the archive directory just keeps growing. It is currently at 392GB. What is the proper maintenance to keep that under control? It does not seem necessary to have that much archived. We are doing regular backups (pgdump). Any suggestions. The WAL configuration is the following:
wal_keep_segments = 1000 << I also think this is unnecessary as well should be much less in my opinion but shouldn't this deep 1000 16MB WAL files or 16GB?
