Does Version 9.1 Streaming Replication Supports Multi-Master?
Started by Jerry Richardsabout 14 years ago2 messagesgeneral
I know PostgreSQL version 9.1 supports built-in streaming replication. Just wondering if that supports only a single-master or also multi-master implementation?
Thanks,
Jerry

master -> readonly slave only.
Master-Master replication is a giant can of worms, with thorny issues of
conflict resolution that can't be resolved in a general case without
massive performance impacts.
