Re: Interrupted streaming replication - Mailing list pgsql-general
Thank you very much, this is working perfectly. I copied a couple over and the server applied them, and is waiting for the next set.

As long as you have 00000001000000890000002C and the subsequent WALs in your archive directory, then you should
be able to simply scp them to you second slave's pg_xlog directory.

Thank you. I'm still running 9.1, but I'll look into 9.4. Fortunately my database is small so doing a new base backup is not the end of the world. It's been a long time since I've set this up, so I'm going to have to go through a refresher course on exactly what I need to do.
Thanks for your help.
