Hey All,

Is it possible to create WAL archive files on standby servers when using streaming replication?

I know I can use archive_command or pg_receivexlog - but these will both result in me sending information to the standby servers which has already been sent via standard streaming replication. This would result in a doubling of my network traffic.

Ideally I'd prefer to conserve this bandwidth and write the files to a local archive on any active standby.

Cheers,

James Sewell,
Solutions Architect
