Re: [HACKERS] [GENERAL] Enable WAL Archive in Replication server

2013-08-11 Thread Jov
now you can only enable WAL archive on the Master server,it will not take effect on replication server. I can't find the doc which explicit prohibit WAL archive on the replication server,and there are WAL generated in the slave pg_xlog dir with archive_status subdir,so I think this may be a bug.
