"It (BDR) has significant advantages - and some disadvantages - when compared to PostgreSQL's older physical (block-based) streaming or archive-based replication with warm or hot standby" What exactly is block based? Changes are recorded in the redo log, right? Does that mean that in streaming replication, from redo log the server applies changes at the block level of the data-file. That would also mean that at any time, both primary and standby would be exactly same, block by block. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
