Previously repmgr was attempting to make replication connections with "dbname" set to the repmgr database name. While this works if e.g. the repmgr user also has replication permissions, it will fail if a dedicated replication user is specified, who only has permission to access the virtual "replication" database. Change this to use "dbname=replication" if the replication connection user is different to the normal repmgr database user. (We could just always set it to "replication", but that might break existing installations e.g. where a .pgpass file is in use and there's no "replication" entry for the normal repmgr database user). Addresses GitHub #421.
repmgr: Replication Manager for PostgreSQL
repmgr is a suite of open-source tools to manage replication and failover
within a cluster of PostgreSQL servers. It enhances PostgreSQL's built-in
replication capabilities with utilities to set up standby servers, monitor
replication, and perform administrative tasks such as failover or switchover
operations.
repmgr 4 is a complete rewrite of the existing repmgr codebase, allowing
the use of all of the latest features in PostgreSQL replication.
PostgreSQL 10, 9.6 and 9.5 are fully supported. PostgreSQL 9.4 and 9.3 are supported, with some restrictions.
repmgr is distributed under the GNU GPL 3 and maintained by 2ndQuadrant.
BDR support
repmgr 4 supports monitoring of a two-node BDR 2.0 cluster on PostgreSQL 9.6
only. Note that BDR 2.0 is not publicly available; please contact 2ndQuadrant
for details. repmgr 4 will support future public BDR releases.
