repl_mon, custom bgworker for PostgreSQL ========================================= Background worker which writes current timestamp, current xlog location and number of streaming replics to a certain table every certain interval of time. It is useful for monitoring replication of PostgreSQL instances: - in seconds, not only in bytes, - without the need to have superuser option for monitoring user. This worker can use the following parameters: - repl_mon.interval, time (ms) between writing information to table. - repl_mon.table, name of the table to write data to, default is "repl_mon". This worker is compatible with PostgreSQL 9.3 and newer versions. More info could be found in this blog entry -- https://simply.name/postgresql-replication-monitoring.html.
