Hi!
Would it not be easier to just set up another Debian server, run binary replication
Breaks occurs rarely, 0-2 times per year. I want try it first.
and put them behind something like pgpool?
Backup server will use single core and minimal RAM. It may be needed 0-2 times per year.
pgpool should switch to use it for production work only if main server does not respond.
I havent found this feature in pgpool documentation (maybe missed).Andrus.
