Free Cache Memory (Linux) and Postgresql - Mailing list pgsql-general

Hi.

I'm evaluating to issue the drop_caches kernel command (echo 3 >
/proc/sys/vm/drop_caches) in order to free unused pagecache, directory
entries and inodes.

I'm thinking to schedule the command during low load moments after
forcing a sync command.

I wonder if this can cause pgsql problems of any kind. Any idea?

Thank you in advance,

Denis Gasparin
