Look at https://bucardo.org/Bucardo/ , BDR (e.g. = https://www.2ndquadrant.com/en/resources/postgres-bdr-2ndquadrant/ ), = RubyRep or any of the other multimaster solutions at = https://wiki.postgresql.org/wiki/Replication,_Clustering,_and_Connection_P= ooling#Replication . You probably don't actually need bidirectional master-master = replication, though, and might want to look hard at other ways to do = what you want. Cheers, Steve=
