Re: WAL retention

Hi,

I use version 9.4.
If I create physical replication slot, I'll need standby server to use it.
I can use pg_receivexlog but it will not prevent removing WAL files, it
will just stream it to some other location.
Do you maybe have an idea how backup can use replication slot (without
standby)?

Regards,
Slavcho
