In this thread, I outlined an idea for reducing cost of WAL CRC checking http://archives.postgresql.org/pgsql-hackers/2006-10/msg01299.php wal_checksum = on (default) | off Recovery can occur with/without same setting of wal_checksum, to avoid complications from crashes immediately after turning GUC on. Patch enclosed here against CVS HEAD, passes make check. Useful reduction in CPU for both normal operation and recovery. -- Simon Riggs EnterpriseDB http://www.enterprisedb.com
