Fatal error after starting postgres : sys identifiers must be different - Mailing list pgsql-www

Hi Alvaro,

 

Could you please let me know what does the error "system identifiers are same" mean? Below is the snapshot from one of the masters.

I am setting up BDR as per the wiki

  http://wiki.postgresql.org/wiki/BDR_User_Guide#Initial_setup

and source @

 git://git.postgresql.org/git/users/andresfreund/postgres.git
