When a binlog is replayed into a server, e.g.: $ mysqlbinlog binlog.000001 | mysql it sets a pseudo slave mode on the client connection in order to server be able to read binlog events, there is, a format description event is needed to correctly read following events. Also this pseudo slave mode applies to the current connection replication rules that are needed to correctly apply binlog events. If a binlog dump is sourced on a connection, this pseudo slave mode will remains after it, what will apply unexpected rules from customer perspective to following commands. Added a new SET statement to binlog dump that will unset pseudo slave mode at the end of dump file.
